FireFox can be uninstalled and reinstalled without bookmarks, preferences, and losing settings?

All of a sudden, I am is more directed to my homepage when opening Firefox. All I get is "the address is not valid. Also, when I choose options, new window, new window private and find, I also get the error "the address is not valid.

I've refreshed Firefox, which did not help, disabled modules, check the updates and open in safe mode, which none helped. I ran various malware and virus scans and empty came to this end.

I was thinking about uninstalling and reinstalling Firefox, but I'm afraid that I lose my bookmarks, preferences, settings, etc. Any suggestions?

Yes! This is a good way to replace the Firefox program files without disturbing your settings:

Clean reinstall it

We use this name, but it isn't about deleting your settings, this is to ensure that the program, files are clean (not incompatible, corrupt or exotic code files). As described below, this process does not disrupt your existing settings. Don't uninstall NOT Firefox, that does not need.

(1) download a fresh Installer for Firefox 39.0 of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

(2) close Firefox (if applicable).

(3) to rename the program folder, either:

(Windows 64-bit folder names)

C:\Program Files (x86)\Mozilla Firefox

TO

C:\Program Files (x86)\OldFirefox

(Windows 32-bit folder names)

C:\Program Files\Mozilla Firefox

TO

C:\Program Files\OldFirefox

(4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.

The pages "internal" work normally again?

Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins
