IN Lately There's a clear trend for Chrome users to switch back to . This is explained by Chrome's excessive appetite for system resources and the rejection of some features of Google's policy, which seems to seriously intend to make it a full-fledged operating system. Well, Firefox is not a bad choice. Especially if you upgrade its security using the extensions from this review.

HTTPS Everywhere

What is HTTPS? This is the most secure web surfing protocol available today, which encrypts all data transferred between the server and the browser using SSL/TLS algorithms. Thus, even if someone intercepts them, they will not be able to read and use them. The HTTPS Everywhere extension forces your browser to use this protocol all the time. Currently, the extension works successfully with almost all popular resources, so we highly recommend installing it.

Ghostery

This extension is so popular and its work is so effective that if I were the Firefox developers, I would have included its functions in the standard browser features a long time ago. Ghostery detects and blocks all extraneous elements on the page, such as buttons and widgets social networks, counters, scripts and much more. In addition to ensuring your privacy and confidentiality, this leads to a noticeable increase in page loading speed to the naked eye. An absolute must-have for every fox breeder.

Disconnect

Disconnect, like Ghostery, allows you to remove web trackers that follow you from pages and prevent them from collecting information about your preferences. The developers included in the extension database data on more than 2,000 tracking elements, blocking which allows you to increase the speed of opening sites by 27%.

NoScript

This addon allows you to stop active scripts from running on various websites until you specifically allow them. This may be inconvenient in some cases, but in the long run it greatly improves surfing safety. It is possible to add trusted domains to the white list.

Blur

Previously known as DoNotTrackMe, this extension is one of the best for protecting your data. Not only does it prevent sites from collecting information about you, but it also protects your sensitive information, such as passwords accounts or payment information.

KeeFox

Most modern browsers have built-in password management solutions, but they rarely work as well as dedicated solutions. So be sure to check out this extension, which will add integration to Firefox with one of the most powerful password managers, KeePass. Start using it if you haven't done so before.

BetterPrivacy

Despite the fact that this extension has not been updated for quite a long time, it is still one of the most necessary ones. This is because BetterPrivacy can handle special cookies, which are also called Local Shared Objects, LSO. They are used by many companies, including Google, YouTube, Ebay, to track user movements on the Web. Now you can selectively or completely get rid of these spies.

Self-Destructing Cookies

Several years ago, real hysteria raged on the Internet and the computer press about the dangers of cookies. If you also think that they pose a threat to your security, then do not miss the Self-Destructing Cookies extension. As the name suggests, it ensures that cookies self-destruct as soon as you leave the page that provided them. There is a white list for verified sites.

Bloody Vikings!

Ignore the bloodthirsty name of this expansion, it has nothing to do with the games. With its help, you can not use your email address when registering on sites, but use one of the many services that offer one-time emails. You just need to right-click on the email input field and select a service in the context menu, where a temporary mailbox will be automatically created. It will then open in a new tab and you can receive your confirmation email and then forget about it forever.

Clean Links

This is an essential extension that should be in every Firefox user's arsenal. It can recognize sponsorship, affiliate and all other “crooked” links and turn them into normal ones. In other words, if you are asked to click on a link like http://www.foobar.com/goto=https://www.yoursite.com, then thanks to the Clean Links extension it will turn into https://www.yoursite.com/.

What extensions do you use for online security and privacy? Or do you not bother with such problems at all?

Mozilla Firefox(or simply Firefox) is a free web browser with open source. There are many add-ons released for Firefox, some of which provide privacy and security while surfing the web.

• How to work with a stable and secure Internet browser that has many add-ons.
• How to protect yourself from potentially unsafe programs and malicious websites.
• How to securely remove digital traces of your online work.

1. Getting to know Firefox

We assume that the reader is already familiar with the web browser, and will not describe the basic functions of Firefox. Let's pay attention to the settings and additions related to security.

1.0. What you need to know about Firefox before you get started

Firefox supports many additions. They are easy to use and provide security and privacy while surfing the web. Depending on your situation, you can choose which add-on to install and how to configure it. If you work on a computer that is controlled by another person (for example, in an Internet café or an office workstation), you may need to set up the program more than once.

In addition to basic Firefox settings, this guide covers installation and basic setup the following additions:

You can select a default search engine and determine which search engines will be available in the Firefox search box. We recommend DuckDuckGo as default search. This system does not track users and does not share user data with third parties.

Some other "security focused" search engines that can be added to the list search engines in settings Firefox:

2.3. Privacy settings

You can change Firefox privacy settings as follows:

Step 1. Select paragraph [Settings]

Step 2. Select paragraph [Privacy] in the left column of the settings window.

Image 1. Firefox privacy settings

You can now change Firefox settings regarding privacy, third-party tracking, and browsing history. Follow these steps:

Step 3. Many websites collect information about you. They allow third parties to track which websites you visit. System Do Not Track allows you to avoid tracking by websites you do not visit, including data analytics services, advertising networks and social platforms.

To turn on Do Not Track V Firefox and keep surveillance of your online activities to a minimum, select two options in the section Tracking. It is important to understand, however, that companies have the ability to ignore your choice and will still track you. Here list companies that have declared their respect for those who ask them do not track.

Step 4. In chapter Story you can manage settings browsing history Firefox. By default the browser is configured remember the history of visited pages and downloads. It means that Firefox will remember the history of pages, downloaded files, completed forms and search queries. The browser will also accept cookies from websites you visit. Cookies allow sites to record information on your device, and Firefox will share information with these sites and their advertising partners.

To prevent this from happening, in the very first option of the section Story- line starting with Firefox:- You can change option will remember the story on won't remember history. You can choose third option will use your history storage settings to configure browser behavior in more detail in the section Story.

• block sites suspected of attacks,
• block sites suspected of fraud.

Options in the section Logins refer to Firefox's built-in password manager. If you check the box Use master password Firefox will encrypt the website passwords it stores and prompt you master password. In general, we recommend using an offline password manager like KeePassX to store your passwords. However, if you decide to use Firefox to store website passwords, you should check the Master Password option.

2.5. Settings for advanced users

You can change settings for advanced Firefox users - follow the steps:

Step 1. Select paragraph [Settings] from the menu at the bottom of the Firefox browser.

2.6 Using privacy settings while surfing the web

In addition to the settings described earlier, Firefox offers two important options: they allow you to have some control over the data Firefox stores on your computer and data about the sites you visit. These are the functions Delete recent history And Private browsing mode.

Delete recent history

To delete recent browser data, follow these steps:

Step 1. In the Firefox menu select [Magazine] as shown in the picture below:

Image 1. Journal item in the Firefox menu

Step 2. In the drop down menu click [Delete history...].

Image 2: Deleting recent Firefox history

Image 4: Delete all Firefox history

Step 5. Select [Delete now] to delete the selected data.

Instead of the steps described, you can use private mode . In this mode, Firefox will not record history at all.

Private browsing mode

To prevent Firefox from storing data about your current browser session, follow these steps:

Step 1. In the Firefox main menu select paragraph [Private window] as shown in the illustration below:

Image 5: Opening a new private window in Firefox

Step 2. Open websites in this window.

Image 6. Using a private window in Firefox

When you're working in a private window, Firefox doesn't record your web surfing data. This applies to any tabs that are already open or will be opened in this window. There are exceptions for the private window - downloadable files and bookmarks. The window also doesn't let you forget that Firefox itself can't stop those who might be snooping on your Internet connections (including your ISP) to find out what websites you visit. To solve this problem, you will need Tor Browser.

3. Firefox Add-ons

Firefox has add-ons that add new options or expand existing functionality. Add-ons include plugins, such as Adobe Flash , And extensions, such as NoScript. In this section, we'll show you how to disable potentially harmful plugins, and then demonstrate several useful add-ons to enhance your privacy, including:

You can agree by clicking the button [Allow...] in the top right corner of the browser window as shown in the image below. Nevertheless, We recommend turning off Flash completely.

Image 6: Firefox warns about Flash material

3.2. HTTPS Everywhere

HTTPS Everywhere – addition which helps Firefox connect securely to websites that support encryption.

When you access a site at an address starting with "http://" (for example, http://www.amazon.com), your connection is not encrypted. Information you send to and receive from the website may be viewed by anyone with the ability to monitor your online traffic. For example, your (ISP) and many surveillance platforms.

When the address begins with "https://" (for example, https://www.amazon.com), your connection is encrypted. It will be extremely difficult for strangers to intercept the data you send and receive. Unfortunately, even sites that support https, often make mistakes by redirecting visitors to the right addresses. This problem is solved HTTPS Everywhere.

U HTTPS Everywhere there is a list of websites that support https, and automatically requests an encrypted connection for these websites, even if you click on a link starting with http(or entered such an address into the browser line).

to install HTTPS Everywhere, follow the steps:

Step 1. Select paragraph [Add-ons] in the browser menu, as shown in the illustration below.

Step 2. Dial Name

Image 2. Search HTTPS Everywhere

Step 3. Click [Install] Near HTTPS Everywhere.

Image 3. HTTPS Everywhere Add-on

Wait while the HTTPS Everywhere add-on is installed.

Image 4. Installing HTTPS Everywhere

Image 5. HTTPS Everywhere add-on installed

When you restart your browser, you will be able to determine whether you need to enable EFF's SSL Observatory, a tool that will alert you to unsecure connections or attacks on your browser.

Image 6. SSL Observatory

Step 5. Click [Yes] to use SSL Observatory for greater privacy protection.

Step 6. Make sure the HTTPS Everywhere add-on is installed correctly. To do this, select items in the Firefox menu [Add-ons > Extensions]. The list of extensions should include HTTPS Everywhere, among others.

Image 7. HTTPS Everywhere add-on installed

The installation of HTTPS Everywhere is complete. When you try to visit one of the websites included in this add-on, if that website supports https, your connection will be automatically encrypted.

Note. When HTTPS Everywhere works, you still You will see "https://" in your browser's address bar. If it doesn't, your connection is not encrypted.

3.3. Privacy Badger

3.5. NoScript

When you visit a website, your browser automatically downloads the content of the site's pages. In addition to text and images, this often includes scripts, small programs that run inside the browser. NoScript – addition For Firefox, which prevents the browser from running such programs without your permission.

Basically, these scripts are harmless. Their task is to increase the interactivity of web pages. However, some are dangerous, while others know how to collect information about your online activities; these are the so-called third party trackers .

Unfortunately, NoScript is not able to automatically determine which scripts are safe and which are not. If you first select the total blocking option ( Block Scripts Globally), many sites will not display correctly. On the other hand, adding different sites to White list, you will gradually bring the situation back to normal and at the same time be protected from potentially harmful content on the network.

To install NoScript, follow the steps:

Step 1. Select [Add-ons] in the browser menu, as shown in the illustration below:

Image 1. Firefox Add-ons

Step 2. Dial Name V search bar in the Firefox Add-ons window.

Image 2. Search NoScript

Step 3. Click button [Install] next to NoScript.

Image 3. Installing NoScript

Step 4. Click [Restart now] to restart the Firefox browser and complete the NoScript installation.

Step 5. Make sure the NoScript add-on is installed correctly. To do this, in the Firefox menu, select items [Add-ons > Extensions]. The list of add-ons should also include NoScript.

Image 5. NoScript add-on installed

Your browser now supports NoScript and can block malicious code if it appears on your computer.

NoScript may seem a bit inconvenient at first (sites you're used to visiting will be garbled), but you'll quickly be rewarded by automatically blocking annoying ads, pop-ups, and malicious code embedded in website pages.

NoScript works quietly in background. When the add-on detects the presence JavaScript elements, Adobe Flash or other scripts, these elements are blocked, and an information bar appears at the bottom of Firefox. NoScript tells you what kind of object you are talking about (for example, an ad or a pop-up window) and what script is blocked in the system. However, because NoScript does not differentiate between malicious and benign code, some important parts of the site (such as the toolbar) may not be visible.

Image 6. NoScript Dropdown Menu

Some websites display elements (including scripts) from other sites. For example, sites like www.twitter.com contain scripts from two sources (twitter.com and twimg.com). To unblock scripts in such situations, try choose option Temporarily allow[site-name] (in in this example– Temporarily allow twitter.com). If it doesn’t work right away, then through trial and error you can get the main sites with the information you need to look normal. For example, for Twitter to work, you need choose options Temporarily allow twitter.com And Temporarily allow twimg.com. If you frequently visit a particular site and trust its content, select option Allow [website-name]. In this case, NoScript will consider the site trusted without a time limit.

Step 6. You can continue configuring NoScript permissions, pressing button [Settings] next to NoScript in the list of extensions (or choosing paragraph [Settings] in the NoScript drop-down menu in your browser).

Image 7. NoScript settings

Note. Recently a vulnerability was discovered in NoScript. We still recommend NoScript because this vulnerability is not dangerous as long as you Also did not install a separate (initially malicious) add-on. We strongly advise you to carefully study add-ons before installing and remove any add-ons that you do not need or have doubts about.

4. Portable Firefox

4.1. Differences between installable and portable versions of Firefox

The portable version of the program cannot be installed on your computer. Her very presence may not leave any traces. But in general portable programs as secure as your external devices, USB flash drives and gadgets. Risk of infection by viruses, spyware and other malicious code is saved.

Functional differences between portable version of Mozilla Firefox and there is no installable program.

FAQ

Question. Why are there so many different add-ons needed to protect against malicious websites? For example, if NoScript protects against dangerous scripts, why other add-ons that work in much the same way?

Answer. Often good advice is to use several tools to solve a particular security problem (except for antiviruses, since these programs tend to conflict with each other). Firefox add-ons are very useful different technologies to protect your browser from threats. For example, NoScript blocks all scripts from unfamiliar sites, but the user can exclude a frequently visited site from being suspicious - and, if he makes a mistake, be vulnerable to a number of threats. The user can also temporarily allow an unfamiliar site to load scripts if they are necessary for the page to display correctly.

Safe Mode is a special Firefox mode that can be used to troubleshoot and fix problems. Safe Mode temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes) that might be causing problems. By comparing Firefox behavior in normal mode to its behavior in Safe Mode you may be able to pinpoint the cause of the problem.

Note: Windows users may be familiar with a Safe Mode for Windows. Firefox Safe Mode has no connection to Windows Safe Mode.

The Refresh Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process.

Table of Contents

How to start Firefox in Safe Mode

Click the menu button, click helpClick the menu button, click Help and select Restart with Add-ons Disabled…. Firefox will start up with the Firefox Safe Mode dialog.

Note: You can also start Firefox in Safe Mode by holding down the shift key while starting Firefox. holding down the option key while starting Firefox.quitting Firefox and then going to your Terminal and running: firefox -safe-mode
You may need to specify the Firefox installation path (e.g. /usr/lib/firefox )

Safe Mode window

You now have two options:

• Clicking the Start in Safe Mode button will temporarily disable your extensions and themes, turn off hardware acceleration and reset toolbar and button customizations. When you leave Safe Mode and start Firefox up normally, your extensions, themes, and settings will return to the state they were in before you entered Safe Mode.
• Clicking the Refresh Firefox button will restore Firefox to its factory default state while saving your essential information. See Refresh Firefox - reset add-ons and settings for more information about this option.

Troubleshooting problems in Safe Mode

Once Firefox is in Safe Mode, you"ll want to test its behavior and see if the problem goes away.

The problem happens in Safe Mode

If the problem still happens in Safe Mode, it is not being caused by an extension or theme. Other possible causes could be plugins or changes made to Firefox preference settings, which are not disabled in Safe Mode. See the following articles for solution:

The problem does not happen in Safe Mode

If the problem does not happen in Safe Mode, it is most likely because of an extension, theme or hardware acceleration.

The issue of security and anonymity on the Internet remains the most pressing and most discussed. What data do websites collect about us when we visit them, who is watching us and how, but most importantly - do I need it? Each website, when visited, leaves small traces on our computer. text files(cookies), which store sessions, passwords, information about various settings, how much time we spend on the Internet, what sites we visit, what banners we click on, etc.

You can use Firefox's incognito mode, which provides a certain level of anonymity. But the Internet service provider is required by law to record all user activity on the Internet. It is impossible to hide from this. But still, most spyware cookies and scripts can be neutralized with add-ons for Firefox.

List of add-ons

Ghostery- Tags, cookies, Web bugs and Web beacons on websites - all these tools monitor your online activities. Ghostery “detects” spies. With Ghostery, this surveillance will stop. Ghostery helps not only block unwanted cookies, but also gives full information about what each specific site is trying to bait you with..

NoScript — Firefox extension, which blocks the execution of JavaScript, Java applets, Flash, and other potentially dangerous components of HTML pages until the user allows their execution on a given node or globally. NoScript also allows users to maintain whitelists (English) of sites that are allowed to use this opportunity. Plugin management is possible regardless of scenarios. Another feature of NoScript is to protect the user from XSS attacks, with the ability to generate separate lists of servers that require functionality similar to an XSS attack. NoScript is one of the ten most popular Firefox extensions

BetterPrivacy— a plugin that allows you to remain unrecognized. If you're still wondering why you can still be tracked despite your best efforts to remove your traces, then BetterPrivacy is for you. It allows you to clear usually unremovable traces on your computer (cookies, etc.) that appear as a result of visiting Google, YouTube, Ebay.

Distrust- this plugin provides complete removal all information that was added to the browser while you were browsing the Internet. Distrust disables the browser cache (both regular and SSL), sets cookies to expire until the end of the session, clears the history of visiting pages and downloaded files, notifies you about the presence of files that you downloaded during the session but did not delete from hard drive, and also deletes all saved logins and passwords.

Stealther- Plugin for safe surfing the Internet. Stealther prevents the browser from storing information about the sites you visit, Cookies, keeping a history of downloaded files, caching sites, saving form information, not saving history of recently closed tabs and send Referrer Header headers. An excellent plugin if you want your browser to not be able to show information about your Internet activities to anyone. Unlike similar extensions, this plugin does not erase information, but rather disables the above features by changing configuration variables, for example

browser.history_expire_days = 0 browser.cache.disk.enable =
FALSE network.cookie.cookieBehavior = 2
browser.sessionstore.max_tabs_undo = 0 and others.

Panic- The plugin allows you to instantly hide all open tabs - you just need to click on the icon. All tabs can be restored later. Clicking the Panic icon again restores all hidden tabs.

Spamavert.com- Generates temporary email address for registration forms, for example on forums.

Adblock Plus- this add-on will allow you to take back control of the Internet and see it the way you want. For the extension, there are over forty filter lists for dozens of languages ​​that will automatically configure it for a variety of purposes, from blocking ads to blocking all known dangerous domains. Adblock Plus It also allows you to add your own filters using a variety of useful tools, including a context menu for blocking images, a shortcut for blocking Flash movies and Java applets, and an element list for removing invisible elements (such as scripts or styles). Starting with Adblock Plus 2.0, it became possible to allow some unobtrusive advertising in the filter settings. In this way, you can support pages that do not force advertising on visitors. We hope this will result in more pages using non-intrusive advertising.

WOT - Safe Surfing warns about suspicious sites (which may contain exploits, spyware, adware and viruses; unreliable online stores; phishing sites, spam and other online scams) before visiting them. Uses a list of 21 million websites. Can set child protection levels by blocking inappropriate content.

FoxyProxy Standard- this is the user's ability to hide his real IP address while traveling around global network Internet. FoxyProxy Standart will help you quickly and easily change IP addresses and remain unnoticed. In practice, FoxyProxy standard is a program that hides IP, but only when visiting sites, and not in general for all applications and programs.

Due to the rise in terrorist activity, authorities in different countries are trying to control as much as possible the behavior of potentially dangerous people and groups by all available means. Moreover, if in developed democracies the judiciary is already sounding the alarm, trying to counter the excessive interference of intelligence services in the private lives of citizens (see, for example, the May decision of the US Supreme Court on the illegality of recording telephone conversations forces of the NSA), then in Russia, due to the virtual absence of separation of powers, this does not happen at all. However, the result is the same everywhere: the “competent authorities” do not intend to retreat, and under plausible pretexts they are increasingly invading the personal life of the common man.

Of course, as Newton noted, every action gives rise to reaction, so some of the most popular applications, extensions and network services today are tools for ensuring anonymity and bypassing all kinds of surveillance systems and limiting user actions. And if real terrorists skillfully hide behind a variety of hardware and software systems, then behind simple user his own browser successfully spies, through which you can quite quickly and without unnecessary tricks collect complete and reliable information not only about lifestyle and political preferences, but also about movements and plans for the future.

We will not talk here about specialized browsers like Epic or Tor - this is a completely separate big topic. Let's talk about the familiar and well-known Firefox. Why about him? The fact is that of the Big Five - Internet Explorer, Firefox, Chrome, Opera, Safari - this is the only truly free and open source browser. Anyone can personally verify the absence of any bookmarks or secret passages left by the developers in order to gain remote control over the user’s actions.

However, a browser alone is not enough to ensure your own network security. We will need various extensions and plugins that perform their narrow but very important functions. Which ones should you definitely install on your Firefox?

1. HTTPS Everywhere

The main advantage of this plugin is that it is able to delete cookies immediately after closing the tab: while the tab is open, cookies exist, and after closing it they are immediately destroyed. This deletion method allows you to effectively deal with types of files such as Zombie-cookies, which are restored from backup copies outside the browser, or cross-browser supercookies Evercookie, which are stored in eight places at once. The extension provides a whitelist for sites whose cookies you do not want to delete.

10. Bloody Vikings!

Under the strange name "Bloody Vikings!" The most useful Bloody Viking expansion is hidden! , allowing the use of disposable addresses Email to protect against spam.

With online services like 10MinuteMail and AnonBox, you get temporary mailboxes With limited time actions by which you can, for example, register on various sites and receive confirmation emails without disclosing your real mailing address. After a given period of time, such disposable addresses and mailboxes simply disappear.

11. Clean Links

And finally, a convenient plugin called Clean Links, which allows you to turn complex, long and confusing hyperlinks into clear and understandable options without unnecessary garbage.

Thanks to this extension, you will not end up on a fake phishing site, thinking that you are in your online banking. Or you simply won’t fall for the bait of an unscrupulous webmaster who wanted to trick you into opening a whole bunch of advertising pages.
