NoScript is a Firefox extension that 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.

The Mozilla Firefox browser takes care of user security. The browser has built-in security features for your computer. Alas, this is not always enough. However, it is easy to help the trouble - install an extension that will protect you while surfing the Internet. One of the good options for add-ons that protect you when working in Firefox is NoScript.

The add-on provides additional security by blocking JavaScript, Flash and Java plugins. They are the ones who have a large number of vulnerabilities, which those who create all kinds of malicious programs take advantage of with pleasure. You can download NoScript for free from our website.

Key Features

The add-on icon (blue S) will appear in the upper right corner of the browser. NoScript starts working automatically; you don’t need to launch it. However, you will still be able to control its operation. In particular, add sites that you are confident in and where there is no need to block “suspicious” plugins to the White List. This is very convenient - after all, some sites without Flash and Java will simply open incorrectly.

Even a child can download NoScript in Russian. This is an official add-on for Mozilla Firefox, so it's in the catalog. Find the “Add-ons” section in the menu, enter the name of the extension in the search bar, and after “detecting” it, click the “Install” button. NoScript will be enabled automatically the next time you launch your browser.

Implements DoNotTrack protection by default. Experts are unanimous: Firefox is truly safer with NoScript.

Mozilla Firefox has built-in protection for your computer while surfing the web. However, they may not be enough, and therefore you will need to resort to installing special add-ons. One add-on that will provide additional security for Firefox is NoScript.

NoScript is a special add-on for Mozilla Firefox, aimed at enhancing browser security by prohibiting the execution of JavaScript, Flash and Java plugins.

It has long been known that JavaScript, Flash and Java plugins have many vulnerabilities that are actively exploited by hackers when developing viruses. The NoScript add-on blocks the operation of these plugins on all sites, excluding only those that you yourself add to the trusted list.

You can either immediately proceed to download and install the add-on using the link at the end of the article, or find it yourself.

To do this, click on the web browser menu button in the upper right area and open the section "Extras" .

In the upper right corner of the window that appears, enter the name of the add-on you are looking for - NoScript .

The search results will be displayed on the screen, where the extension we are looking for will be displayed at the top of the list. To add it to Firefox, the treasured button is located to the right "Install" .

You will need to restart Mozilla Firefox to ensure installation.

How to use NoScript?

As soon as the add-on starts working, its icon will appear in the upper right corner of the web browser. By default, the add-on is already doing its job, and therefore all problematic plugins will be disabled.

By default, plugins do not work on absolutely all sites, but, if necessary, you can create a list of trusted sites for which plugins will be allowed to work.

For example, you went to a site where you need to allow plugins to work. To do this, click on the add-on icon in the upper right corner and in the window that appears, click on the button "Allow [site name]" .

If you want to create your own list of allowed sites, click on the add-on icon and in the pop-up window click on the button "Settings" .

Go to tab "White list" and in the “Website Address” column, enter the URL of the page, and then click on the button "Allow" .

If you need to disable the add-on altogether, there is a separate block in the add-on menu that allows scripts to run temporarily, only for the current site or for all websites.

NoScript is a useful add-on for the Mozilla Firefox web browser, with which web surfing will become much safer.

The NoScript extension helps prevent potentially dangerous actions on website pages on the Internet. When visiting various sites on the Internet, on the web pages of the visited sites, various potentially dangerous actions are often performed by components that are located on the open web page.

In order to protect yourself from such actions when using the Mozilla Firefox browser, the NoScript add-on is used, with which you can block the execution of potentially dangerous scripts that may occur on the web page you visit.

By installing the NoScript extension, you will be protected from script execution on the web pages of sites you visit, except for those sites on whose pages you allow their execution. This extension also protects against XSS attacks and ClickJackihg, disables Flash, and hides the computer’s IP address.

Script, or script, is regular program code placed on a web page that allows you to perform some action on that web page. With the help of various scripts, beautiful animation can be launched, mailbox registration, communication on the forum, etc. can take place.

But there are also malicious scripts embedded in web pages that download various viruses and other malicious code onto your computer without your knowledge when you open or are on an infected web page.

The NoScript extension allows you to disable scripts for untrusted sites, thus preventing the possible execution of malicious scripts on the web page you visit. On reliable sites, the degree of reliability of which you determine yourself, script execution will not be blocked.

NoScript Add-on

To install the NoScript add-on, you need to click on the “Firefox” button, and in the “Settings” menu, click on the “Add-ons” button. In the search box “Search among extensions” you need to enter the expression “NoScript”. On the page for this extension, you need to click on the “Add to Firefox” => “Install now” => “Restart now” button.

After installing the extension, you can go to “Settings” to look at the default settings for the NoScript add-on. In the NoScript Settings window, in the General menu, you can check the option “Allow all bookmarked websites to run JavaScript.”

If you have a lot of bookmarks and you trust these websites, then you will not have to set up separate rules in this add-on for each site that you have in your bookmarks.

The “White List” menu already contains some sites included there by default; you can add selected websites to this list yourself by entering the site address in the “Website Address” field, and then click on the “Allow” button. This action can also be performed using the context menu.

You can leave the rest of the NoScript add-on settings unchanged and leave the default settings for this extension.

After enabling the NoScript extension, a panel with an add-on icon in the form of the letter “S” will appear at the very bottom of the Mozilla Firefox browser window. When you click on the "Settings" button on this panel, you can give a command to perform the actions you select.

You can close this panel and perform all actions related to the NoScript add-on from the context menu, selecting the desired action to allow or block the execution of scripts on a specific web page.

If you disable the execution of scripts on a particular web page, you will not be able to see many objects that may be on that page, watch Flash videos, some advertisements and other content of the web page, unless you temporarily allow the execution of some scripts on that page.

You can add a website to the “White List” of trusted websites, on the pages of which scripts will be allowed to run without the NoScript extension interfering with this process.

You can also disable the execution of Java scripts using the Mozilla Firefox browser itself.

To do this, click on the “Firefox” => “Settings” => “Settings” button. In the “Content” tab, you need to uncheck the box next to “Use Java script”. After this, the use of scripts will be prohibited on all web pages that will be opened by the browser.

The difference between using this method of disabling scripts and the NoScript add-on is that you will not be able to control whether scripts are enabled or disabled on a specific web page yourself.

Conclusions of the article

The NoScript extension in the Mozilla Firefox browser disables JavaScript, Falsh, and hides the IP address. The user can independently enable the execution of individual or all scripts on specific web pages.

Let's get started.

A little theory on scripts and security

The fact is that most (if not all) viruses and worms that leak onto our computer from the Internet do this through scripts installed on the site. Of course, this is not the only option, because there are, were, and will be others, but the majority still rely on JavaScript.

JavaScript is a scripting language most often used to create scripts for browser behavior that are embedded in web pages. This is one of the implementations of the ECMAScript language, if of course that tells anyone anything. It is with its help that webmasters implement the display of this or that information on the site, the operation of some programs\execution of various scripts\something else.

On YouTube, if Java is prohibited, the video player window simply does not appear.

It is with the help of this language that it is possible to execute/run malicious code that can harm your computer or download a virus that will cope with this task just as well, and therefore blocking and controlling its execution is one of the key elements of security.

Where to download and how to install NoScript

Of course, it was first necessary to install the mozilka, i.e. the same browser to which, in our article, this extension goes.

If you haven’t done it yet (oh my God!), then follow this one and install this wonderful browser as soon as possible.

Now about the installation process and configuration of the plugin:

• To install the addon, go to its page, namely;
• Click on the “Add to FireFox” button;
• In the pop-up window, wait three seconds and click the “Install” button
• After installation is complete, press the “ Restart FireFox” or restart the browser manually;
• Installation completed. Let's move on to setup and use.

Let us repeat that you can also find it for other browsers, be it Chrome, Opera, etc.

How to set up and use script blocking

Installing NoScript is not enough - you still need to learn how to use it in order to get the maximum benefit from what is installed.

• • In my opinion, you don’t really need to change anything in the settings, but still I would like to give you some recommendations on settings that may be useful to you:
    • On the "Advanced" - "Untrusted" tab, check all the boxes
    • On the "Advanced" - "Trusted" tab, check only the first checkbox
    • On the "Advanced" tab - " XSS (Cross Site Scripting)"check all available checkboxes;
    • On the "Basic" tab you can check the box " Allow all bookmarked websites to run Java Script". This should only be done if you definitely trust the sites in your bookmarks and know that they do not and will never have viruses, malicious code, etc., etc. Personally, I did not check this box and would not particularly recommend it to you. Read more about trust below;
  • After installing the plugin, when you go to any site where there are some scripts, the following thing will pop up:

What else you need to know and understand about scripts and NoScript

• • If something that you need on this site is on it (be it text, a picture, etc., etc.) and works, then you don’t need to touch anything!
  • If, on the contrary, it doesn’t work\works incorrectly\didn’t appear at all\etc., etc., then you will need to click on the “Settings” button and Firstly Allow a script with a name that exactly matches the name of the site address. That is, if you are now on the site, then if something does not work, you allow the script site, and not like dyadyavasya.com. After that, you look carefully to see if what you needed worked? If the answer is yes and everything works as desired, then you don’t touch anything else. If not, then you carefully look at what other scripts there are and select one more from them, allowing it. And so on until the site is fully operational. Try to avoid allowing scripts that bear the names of sites other than this one;
  • Note: if you are not going to visit this site anymore, or you visit it extremely rarely and are not sure of its security, then if you allow any scripts, do it temporarily, and not completely. There is a corresponding point for this:

• I repeat. Be careful and do not allow scripts just like that. This should only be done if something on the site is displayed incorrectly;
• If you allow the script temporarily, then the next time you access the site it will be blocked again and you will have to allow it again. If you simply allow it, then it will be added to the white list and will be completely unblocked.

Afterword

Thanks to NoScript, problems with viruses, worms, pop-ups, installations of left panels for the browser, redirects to other sites, attempts to steal your information and other malicious riffraff will be significantly reduced.

Among other things, a bunch of pop-up windows, redirects, and some advertising will disappear, and the speed of loading sites and moving around them will increase.

If used correctly (it's not that difficult), you will hardly need an antivirus anymore. This is a truly necessary plugin for those who care about their security, the security of their computer and valuable information.

If something didn’t work out or is not clear, write or leave comments. I will help with all I can;)

Noscript plugin for Mozilla FireFox

Currently, the security situation on the Internet is more than tense - malware is posted not only on sites with strawberries and cracks, but also on respectable portals hacked by hackers specifically for these purposes. In most cases, malware is downloaded onto the computer of unsuspecting users using scripts.

For example, register a mailbox, chat on forums, or browse website pages using a beautiful animated menu.

In NoScript settings Lots of options that can make your online experience safer, even with default settings. On the other hand, you will not be able to normally view sites with many scripts without setting up NoScript; some menus may not open, videos and flash may not be shown.
