How to completely clear the mozilla firefox browser. Reset settings in Mozilla Firefox. Create a backup copy

The main purpose of resetting Firefox is to get rid of additional applications and themes. After all, it is they, in most cases, that lead to failures in the search engine. Currently, many extensions are outdated and do not work correctly, some of them do not work at all in .

Reset Firefox settings

Resetting Mozilla Firefox settings in most cases helps relieve the browser from malfunctions. Return to original version With parameters from developers from Mozilla Corporation, you can do two things. The first way is to use the hint contained in the settings menu in the “Information for solving problems” item. The second is to delete the special Jscript file from the service folder Mozilla Firefox on your personal computer. In both cases, the settings are restored to the default settings without affecting data such as:

• Personal data for automatic filling (logins and passwords);
• Opened and saved bookmarks, history of previously visited web resources and download history;
• Cookies;

The first option is through Help

In the settings menu search engine You must click on the “Open Help menu” icon. Next, select an item with detailed technical information about useful solutions to problems with the search engine.

First, you can try restarting the browser in safe mode with additional extensions temporarily disabled. If these manipulations are of little benefit, you can try to thoroughly clean it.

The second option is to delete the configuration files

Open the profile folder, and close the browser itself through the settings menu by clicking on the “Exit Firefox” button. This button is next to the Open Help menu button.

In the profile folder that opens, find the “prefs” files. You can keep the JScript file (just in case) only by renaming it. This way, the user will have a backup to restore the settings. And the rest can simply be deleted.

After deleting these files or renaming them, launch the browser. The JScript script file will be created again in the profile folder, and the settings in the Internet browser will return to the “factory” ones.

The Mozilla Firefox browser may also experience problems. This may happen due to the fact that the user himself has changed some settings or due to problems in the system itself - this may not be your fault.

In order for the browser to continue to work correctly, you need to reset the settings in Firefox. This will mean that the program has returned to the state it was in immediately after installing it on the computer. In this case, the data in the form of bookmarks and passwords will remain in place.

What remains after cleaning?

The profile folder contains all the user’s personal data: themes, add-ons, various parameter changes.

Plugins are not add-ons that you download from the extension store. They are stored in a different folder, so they will remain safe and sound after cleaning.

After the reset, bookmarks, browsing history, downloads, cookies, form data, and open tabs will also remain.

Cleaning occurs within the browser itself. There is no need to download additional software for this. So how do you reset? First, let's launch a tab that helps deal with various technical failures.

4.Confirm that you want to return the settings to default. The window will warn you that this will fix the problems and restore performance, but resetting will also remove add-ons. If you agree to these terms, please confirm your action. Otherwise, click on the “Cancel” button.

The process of resetting all settings may take some time, so do not rush to conclusions that the browser has frozen.

The browser will automatically restart itself. With the new opening, you will find that the browser has returned to its original state, which was after the very first installation. After launch you can do Firefox browser default.
