Web browsers may automatically open the most recently viewed tabs. To enable this feature, you must change your browser settings. If you have set your browser to always open a specific website, that is, your home page, or you always tell it to always open a blank tab, the browser won't load tabs from your previous session. Both Firefox and Chrome support this session recovery feature, but Firefox adds something extra. If you set Firefox to open tabs from your previous session, it will do this. However, it won't load the tabs until you actually visit them. Firefox does this to prevent slow startup. It's best to load just one tab you want to use and set the others aside until you visit them. This feature is called click to load tabs. Here's how you can disable loading tabs in Firefox.
Enable session recovery
Loading tabs only occurs if Firefox is set to open tabs from the last browsing session. To enable this feature, go to Firefox settings by entering the following in the address bar:
A: Preferences
On the General tab there is an option for “When Firefox starts”. Open the drop-down menu next to this option and select "Show my windows and tabs since recently."
Disable download
Now that you have enabled session recovery, you need to disable downloads in Firefox. In the address bar, enter the following:
A: Configurations
Click the "I accept the risks" button to continue. On the About:config page, enter the following in the search bar (not the same as your browser's address bar);
Browser.sessionstore.restore_on_demand
This is the preference that controls the click to download. By default, this value is set to True. To disable loading tabs in Firefox, you only need to double-click this preference to change its value to "False".
That's all it takes. The next time you launch Firefox, all tabs from the previous session will be loaded. You don't have to visit them to start downloading. We should note that this will slow down Firefox when you start it. If you have a good internet connection, this may not be great. For slower connections, disabling click to download is not a good idea.
Many users Mozilla browser Firefox is not happy with the situation in which when starting this browser, instead of opening the last open tabs, the start home page is launched.
This is actually not convenient, because it is always more pleasant to see the last opened tabs when starting the browser in order to finish reading or viewing the necessary information.
In this article we will tell you what needs to be changed in the Mozilla Firefox settings so that all open tabs are saved after closing the browser.
Setting up Mozilla Firefox launch
So, in order to launch open tabs with sites from the previous session when you open Mozilla Firefox, you need to change just one parameter in the settings.
To do this, go to the Mozilla Firefox settings by clicking on the three horizontal stripes in the upper right corner of the browser.
Go to settings
A menu will open in which you need to select “Settings”.
Next, you will see the main Mozilla Firefox settings window, where immediately on the “General” tab, under the line “When Firefox starts,” you need to set the switch to the “Show windows and tabs opened last time” position.
Changing the parameter
After that, close the settings tab and enjoy saving open tabs when launching Mozilla Firefox.
Now you don't have to worry about saving all open tabs in your browser. After all, even in case of incorrect completion Mozilla works Firefox will offer to restore all open tabs to the previous time.

Very often, many users want to restore tabs in Firefox that were opened in the last online session (previous web surfing session). Some comrades remember which sites were opened, but want to save time on loading them. Others are annoyed: “Yesterday I visited such interesting web pages, and today I want to download them all, but I don’t remember the addresses or URLs.” And there are also people working on the Web who, immediately after launching FF, need to restore everything as it was (in the sense of the Mozilla tab) in order to continue working on the project, searching for information, etc.
In this article you will find a comprehensive answer to the question of how to make Firefox save tabs. It discusses various ways saving tabs in Mozilla Firefox and then quickly restoring them.
How to open quickly?
If you have the Mozilla Firefox start page set as your home page in your browser, lost tabs can be opened with just one click when closed.
In the bottom bar of buttons, click “Restore previous session.” After this action, FF will download all saved pages remaining from the previous Internet visit.
The browser’s “branded” page is displayed by default on the start page. But if this setting has changed, you can return it:
1. Open in the menu: Tools → Settings → General.
2. In the “At startup...” line, set the value to “Show home page”.
3. In the “Home pages...” field, remove all links so that “ home page Mozilla..."
Log recovery
After exiting FF, you can return open tabs from the previous session in the web log panel:
1. At the top right of the web browser window, click the “menu” button.
2. In the tiled menu, click “Journal”.
3. In the submenu, select the “Restore closed tabs” command.
Advice! If you had to close a tab or tabs but Firefox window is still open, use the hotkey combination Ctrl + Shift + T to restore closed pages. Running this command again opens the next previously closed tab. This way you can restore your entire online session.
Setting up your browser for automatic recovery
If you want Firefox to load the tabs from the previous session every time you launch it, do the following:
1. In the "Tools" menu, click "Settings", go to the "Basic" tab.
2. In the “At startup...” option, set the “Show windows and tabs opened last time” option.
The last tab closed - FF also closed: how to fix it?
By default, when you close the last tab, Firefox also closes. Often this property causes a session to be interrupted: the user mistakenly closes the last page and, along with it, FF. Then you have to spend time restarting and returning the Internet session.
You can disable this setting like this:
1. In the address bar of the new tab, type - about:config.
2. Under the warning text, click “I accept...”.
3. In the search, enter - closeWindowWithLastTab.
4. Double-click with the left mouse button on the found option so that its value changes from “true” to “false”.
5. Restart FF.
Now you can safely close the tabs; the Firefox window will not close in any case.
Session manager to help
The Session Manager addon provides the ability to quickly save tabs for one or several sessions and open them when necessary. It can be downloaded from the official Firefox add-ons portal.
1. After installing and connecting the manager, open the “Tools” section in the FF menu.
2. Hover over the “Session Manager” line.
4. In the settings panel, give the session a name. Click the “Save...” button.
5. To load closed tabs, open the addon menu again (Tools → Manager) and click on the name of the required saved session. After activating this operation, web pages will load automatically.
Your specific situation will tell you which of these proposed tools to use to restore tabs. But if we are talking about an isolated case, the standard settings of the web browser on the main page or in the web log will do. If there is a constant need to return the session, it makes sense to configure automatic recovery in the Firefox options or use the Session Manager add-on or its equivalent.
Looking at the task manager, many users may have noticed the presence of several firefox.exe processes in memory at once. Why do you need many processes and is it possible to disable them - read on.
So, in the task manager today you can see two, three, four, five or more Firefox processes.
Why does the browser need multiple processes? Multi-process architecture increases security and stability: if a failure occurs somewhere, it will not drag down everything else at once.
In fact, the multi-process technique has been used by other browsers for a long time, and much more aggressively than Firefox. For example, Chrome and all Chromium-based browsers (modern Opera, Yandex.Browser and others) can even show dozens of processes in memory in the task manager if you have many tabs loaded.
There is one serious negative point in this: many processes can put a lot of stress on a weak computer, and if you are used to working with a large number of tabs or have many extensions installed, then even a PC with relatively up-to-date specifications can become strained.
Does Firefox create fewer processes than Chrome?
As we have already said, Mozilla approached the issue of multiple processes much more carefully than Google itself.
Initially, the developers created only one additional process for Firefox, where plugins (not to be confused with extensions) were displayed - plugin-container.exe. Thus, Firefox has 2 processes for the first time.
However, time passed and required the company to not be inferior to its competitors in terms of stability and security. As a result, the long-tested, full-fledged Firefox multi-process architecture was completed this year.
Firefox does not lose the advantage of lower memory consumption, even if it uses its multiprocessing to the maximum (8 CP - 8 processes for processing content)
Some users of stable versions of Firefox were able to appreciate multiprocessing for the first time this summer, starting with Firefox 54. The final stage here was the autumn release of Firefox 57, which no longer supported . Some of these extensions could previously block multi-process mode, forcing Firefox to use only one process.
However, with processes in Firefox, things are still not the same as in Chrome. If Google's brainchild launches literally everything and everyone in separate processes (every tab, every extension), then Firefox breaks various elements into groups. As a result, there are not as many processes as the main competitor.
This results in noticeably lower memory consumption and, in some cases, lower CPU load. After all, a huge number of processes in Chromium browsers can load even the weakest processor. But Mozilla eventually came to a compromise and, in our opinion, the most reasonable solution.
Additionally, Firefox uses a different on-demand tabs mechanism than Chrome and Chromium-based browsers.
If these web browsers automatically sequentially load tabs from the previous session in the background, then the “fire fox” does this only when explicitly accessing (clicking) on the tab, thereby not creating unnecessary processes when they are not needed. This also contributes to less resource consumption.
How to reduce the number of Firefox processes?
Unlike Google, Mozilla practically allows the user to control how many memory processes the browser uses.
You see several firefox.exe processes (or firefox.exe *32 in the case of using 32-bit versions) hanging in the task manager and want to remove/disable them - no problem. Open Settings, scroll down the “General” section, reaching the “Performance” subsection:
If you uncheck the "Use recommended performance settings" option, you will be presented with a setting for the number of content processes.
There are options from 1 to 7 processes to choose from (if you have more than 8 GB of memory, then more than 7 processes may be offered):
At this point it is worth making several important clarifications.
Firstly, we are talking about processes for processing content. If you specify here, for example, only 1 process, then the total number of processes in memory will decrease, but you still won’t get only one copy of firefox.exe, because in addition to the content, Firefox also outputs interface processing to separate processes.
Secondly, reducing the number of processes makes sense on computers with a small amount of RAM and extremely weak hardware. In turn, on more or less acceptable hardware, multiprocessing will not worsen performance, but, on the contrary, will contribute to it, albeit at the cost of increased memory consumption.
Is there any benefit to reducing the number of processes?
If we talk about our own example, for a PC with 8 GB of RAM, 4 content processing processes were initially proposed. At the same time, up to 7 processes could be displayed in memory when opening a large number of tabs.
When we set the number of content processes to 1, restarted the browser and re-clicked on all the tabs to load them, predictably only 4 processes remained in memory.
Of these, 3 are intended for the browser itself and 1 process is specifically for processing content, and the latter is easy to distinguish, because when you open a decent number of tabs, it begins to take up much more memory than the others:
In Firefox, we had 15 different sites open. In the original mode (7 processes), the total memory consumption was about 1.5 GB. When there were only four processes left, in total they took about 1.4 GB (see screenshots above).
We repeated the experiment several times, each of them a “win” random access memory was only 100-150 MB. It is worth considering that browser performance could be reduced by switching to 1 process for content. Thus, as you can see, the point of reducing the number of processes is very small.
Everyone knows: tabs allow you to open an unlimited number of sites in one window. This keeps your screen uncluttered and makes it easy to switch between web pages. Today I will touch on the issue of organizing tabs through browser settings and talk about little-known ways to optimize work.
First, visit the page with the main settings of the application by typing in the address bar about:preferences#general and pressing " Enter" (cm. " Tools" → "Settings"→ section" Basic").
In the corresponding subsection "Tabs" there are four settings. Active web surfers, who usually have dozens of sites open, often activate only " Open links in tabs instead of new windows". The fact is that switching to the tab that opens when visiting portals like Avito and YaPlakal is inconvenient, and the page thumbnails on the taskbar and in the "Ctrl + Tab" mode are not informative. However, try all the options and choose the best one for yourself.
Optimizing Firefox using about:config
About new hidden settings The author learned from English-language sources, i.e. they are not yet known to domestic users. The functionality turned out to be useful, so I suggest address bar enter about:config , press " Enter" and the " I take the risk!" in the browser window. Next, we follow the scheme: copy each of the settings in the search field → double-click to change its value → read the description and try it. If the result is not impressive, double-click to return the default value to innovations that are of little use to you.
- Parameter tabs.loadBookmarksInTabs (change " false" on " true ")
First appeared in, is responsible for opening any bookmark not in the active one, but in a new tab. Which saves a lot of time, because... you don’t have to return to the page you left or open an empty tab specifically for bookmarking.
- Parameter browser. search. openintab (change " false" on " true ")
For and above. Similarly, when searching the Internet using search bar will open a page with results not in the current one, but in a new tab. When combined, i.e. address-search line (see. about:preferences#search) function does not work!
- Parameter bookmarks.openInTabClosesMenu (change " true" on " false ")
For Firefox 59 and higher, via the middle mouse button or " Ctrl + click on the desired bookmark" will open the bookmark in a new tab without closing the menu itself. Which is convenient when you periodically work with bookmarks. When you normally (without "Ctrl") click on the bookmark, the menu safely "collapses".
- Parameter tabs.closeTabByDblclic (change " false" on " true ")
Should appear in the final Firefox versions 61, is responsible for closing the tab using double click by title.
Important!
If you click on the title of the active tab right click, you will find many “one-off” options: “ Move to new window", "Update…", "Mute sound...", "Pin...", "Duplicate…", "Send... to device", "Restore closed...", "Close tab", and " Update all...", "Add all... to bookmarks", "Close others...", "Close tabs on the right".
