Firefox keeps trying to update every time I open the browser, and it then puts up a message saying update was unsuccessful. It does this on both of my computers. One has the latest version, the other does not. How do I stop Firefox from doing this?

Chosen solution

If there are problems with updating then best is to download the full version and uninstall the currently installed version and delete the Firefox program folder to remove any leftover files.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible.

  • Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data because all profile folders will be removed.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
