When Firefox updates and error message comes up telling me to close other windows of Firefox.
There are no other window of Firefox open. Each time I open Firefox the update starts and then come up with the error. I click on no for the update the next time and the window will open without doing the update.

See:
- How to fix the Update Failed error message when updating Firefox
- http://kb.mozillazine.org/Software_Update (Software Update not working properly)
Remove the files in the updates and updates\0 folder:
C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates (%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox\updates)
- Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
- Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
- Don't remove personal data if you uninstall the current version.
- 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 (not in the Firefox program 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.
