If files already have been downloaded then remove the files in the updates and updates\0 folder.

You can also delete active-update.xml and possibly updates.xml (stores the update history).

C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates
(%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox)

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.

  • Uninstall your current Firefox version.
  • Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
  • Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
  • 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 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.
