A web browser, or as everyone is used to calling it a browser, is one of the most necessary computer programs. It is difficult to imagine how you can log into the Internet if the appropriate software. One of the main features of the browser is opening multiple tabs. A rather convenient function that allows you to maneuver across the vastness of the World Wide Web without having to close previous pages.

However, this feature has one small drawback. It is very easy to get confused when there are many tabs open, this will lead to the fact that you simply cannot find the necessary page at the right time. This shortcoming can be easily corrected by simply following some of the rules described in this article. This will help you become a real web browsing guru.

The search engine opens up to us the wonderful world of the Internet. A browser is needed not only for searching for information. Here you can listen to your favorite music, watch movies, read books. Regardless of which one you use, developers try to release updates for these programs as often as possible. But sometimes they fail to correct minor defects.

To optimize your browser performance when you have many different tabs open, you need to use certain functions available in the browser. Even using the same program for a long time, you may not be aware of all its capabilities.

Hotkeys

It is inconvenient to work in the browser when many pages are open. You can accidentally close the necessary one. In such a situation, it would be correct to use hot keys.

• Ctrl+Tab– used to switch tabs to the right.
• Ctrl + Shift + Tab switches between tabs, vice versa, to the left.
• Ctrl+W for operating room computers Windows system Cmd + W (for Mac OS) – closes an open tab.

These abbreviations are the main ones, however, the list is incomplete.

Memory of open tabs

When working on a PC, we don’t always use only a browser. There are situations when work takes place between several programs. Then the browser needs to be minimized and expanded every now and then. In such a commotion, you can easily miss and not minimize the window, but accidentally close the browser. It's good if you remember the pages that were opened. But as practice shows, these are isolated cases, and it is almost impossible to remember their address. Then you have to waste precious time searching for information. An option that allows you to leave pages that were previously closed in memory will help avoid this. Enabling in different browsers:

• Google Chrome : Settings – Starting group – Continue working from the previous place.
• Firefox: Settings – General – When Firefox starts – Show windows and tabs opened last time.
• Apple Safari: Settings – General – Safari opens at startup – All windows from the last session.

Create a list of favorite tabs

Every browser allows you to save important pages in your favorites folder. This is necessary if you have found the information you need, but will work with it later. The program will help you save it in your bookmarks. To add a site, you need to right-click on the open page and select the “Add to Favorites” option in the window that appears. Web browser developers may change the name of this item, but it will still be intuitive. After simple manipulations, the newly added page will appear in your bookmarks. Click the same mouse button on the folder and select the “Open all bookmarks” option - the added pages will appear on the screen.

Placing tabs in different browser windows

Don't forget that you can work in more than one browser window. For greater convenience, the developers have provided the ability to open tabs in separate window. Even a child can perform such a maneuver - you just need to drag the open page using the cursor onto an empty area of ​​the desktop.

Managing multiple tabs

Browsers allow you to work with multiple tabs simultaneously. The Ctrl key will help with this (Cmd if you have a Macintosh). We select the necessary pages with the key held down, and now you can carry out various manipulations with them. You can close, minimize, open in a new window, or save.

Pin a tab to a specific location

Modern browsers have a very convenient function. They allow you to fix the tab in a place convenient for you. For example, if you often have to open mail or some other page, you can pin it at the very beginning, so it will not move when you open subsequent pages. You don’t need to have any skills to learn how to pin pages in the right place, you just need to use the right function key mouse by clicking on the tab and selecting the appropriate option: “Pin tab”.

Restoring a closed tab

When working with a computer, a large number of actions occur automatically. In the hustle and bustle, you can close the tab that you didn’t intend to. Restoring it is quite simple; you don’t even have to go into your browsing history. The shortcut key Ctrl + Shift + T is used in Windows. Cmd + Shift + T for Mac computers in Chrome and Firefox browsers. If you have Safari browser, press Cmd + Z - this will help restore the closed page.

Useful Firefox option

Firefox has a handy option: Tab Groups or Panorama. It simplifies the use of a large number of windows as much as possible. Moving between them is done using the mouse. You can enable tab groups as follows by holding down the keys: Ctrl + Shift + E (Windows) or Cmd + Shift + E (Macintosh).

Is there any extension that allows you to do this? Because when you close a browser with 10-50 tabs and then open it, what happens is: the cores are loaded to 100%, everything is terribly stupid and it’s impossible to use anything until Chrome deigns to load all the tabs. In general, you need all tabs except one to be frozen. And they began to load as they switched to them.

So I need them all to open from the previous session, but not all to become active right away.

This is how it happens in Firefox by default; is Chrome used to it anyway?

The thing is that Firefox uses the model "one process - many branches"

Chrome takes the opposite approach, splitting tasks across multiple processes. As a result Google process Chrome Renderer uses 100% CPU all the time.

The advantage of this approach:

Chrome uses a multi-process architecture, and each tab or plugin, in most cases, has its own process. This procedure, called process isolation, eliminates the possibility of tabs interfering with each other. Also, an attacker using one tab will not be able to see what is happening in another, and if one tab crashes, this will not interfere with the operation of the entire browser - you just need to close this tab.

Chrome includes a task manager that allows you to see how sites and plugins are using the user's RAM, processor and Internet connection, and also terminate them if necessary.

Chrome is trying to solve another important problem - browser consumption random access memory. Google decided to run a separate process for each open page. That is, in fact, each page will work in its own copy of the browser. This will require a little more resources right away, but in the long run it will eliminate several pressing problems and provide some advantages.

By constantly allocating and freeing small amounts of RAM for page elements, browsers usually quickly fragment the address space allocated to them by the operating system and are forced to ask for more, gradually swelling to completely indecent sizes. In addition, if the processing of one of the pages suddenly fails, the browser will most likely either freeze or stop working.

Multiprocessing largely shifts the problems to the operating system. It will immediately allocate a large piece of memory to the process for one page, and after closing it will completely release the resources. This will not completely protect memory from fragmentation, but the scale will be completely different. Moreover, modern OS they know their business where better browsers. This, by the way, makes it possible to use multiprocessor configurations much more efficiently.

In terms of reliability, this method also works great. By isolating each process, Chrome has complete control over how it runs and can terminate it at any time, preventing the problem from affecting others. open pages. Moreover, the user himself can take an interest in how many resources are consumed by different processes, and, if desired, get rid of the most voracious ones. The same goes for plugins. If, for example, Flash player suddenly it starts to load the computer too much, you can turn it off on the fly.

Chrome runs each tab in a separate process. But this can be changed.

–process-per-tab

This key in the browser launch options specifies to launch each tab in a separate process. This speeds up page rendering and makes the browser more stable, but requires more RAM. This mode is set by default.

Hello Dmitry!Question. In my Chrome browser The session recovery option is enabled and after it restarts, the browser loads all the tabs that were open for me when it shut down. This makes it easier for me to work. But Chrome still noticeably slows down, opening many tabs at the same time. On the Internet, as a cure for such slowdowns, they suggest using the Native Lazy Tabs extension from the Chrome Web Store, but for some reason I didn’t find it there! What solutions can you offer?

If you have the session recovery option enabled in Chrome settings, the browser will load all tabs that remained open when it shut down. Convenient, to say the least, but for this convenience you have to pay sometimes with a noticeable slowdown in the launch of the browser. Several solutions to this problem have been proposed by third-party developers, for example, an extension was available in the Chrome store for some time Native Lazy Tabs, which loads only the active tab when the session is restarted.

However, the tool was not in demand, and the administration removed it from the Chrome Web Store. At the same time, Google decided to create its own tool to optimize the launch of Chrome with saved tabs, which was soon done. Two parameters are responsible for accelerating the start in the experimental browser settings - Infinite Session Restore And Page Almost Idle. To enable the first one, go to the internal address chrome://flags/#infinite-session-restore and set the value for the setting highlighted in yellow to “Enabled”.

Immediately below it is the Page Almost Idle setting, the value of which should also be set to “Enabled”. Then we restart the browser by clicking the “RELAUNCH NOW” button in the lower right corner of the page.

Applying the settings will prevent background tabs from loading at the same time. As a result, launch the browser with big amount The tabs saved in the last session will run without any visible freezes.
