I can't update to version 28.0. The update is not applied.
Firefox is trying apply the partial version of 28.0 - and says it doesn't work. I tried to install the full update, but get the same result.
The same happens with the manually downloaded version. What to do?
Regards / Bengt

Hello BengtC, in your profile folder you have a User.js file.
The user.js file does not exist by default. If you create the file, forget it, if you have not create the file then delete the User.js file, and try to update firefox again (some programs create and write in the User.js file also).
thank you
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
- Firefox 28: http://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
- Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
- (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
