Can't upgrade Firefox because it wants me to close Firefox but Firefox is not open.

more options

I tried several times to upgrade Firefox. The files can be downloaded and saved to the hard drive, but when I launch the upgrade I'm told that I have to close Firefox even though I have already closed it.

This happened

Just once or twice

== after that I didn't try again

Did you look at the Task Manager to make sure FF is not running there? Sometimes even though you have closed FF, it might still be running its process -- alt + ctrl + delete
