I am running version 54.0.1 (32-bit) on Windows 10. I often have problems opening Firefox because old Firefox processes are still running in Windows (despite the application having been closed properly from a UI perspective).

I have tried to upgrade many times. I can't upgrade automatically because the restart of Firefox fails after the update downloads. If I use the installer that I downloaded, I can get to a new version for one session -- today it was 55.0.3 (64-bit) -- but after i close Firefox and re-open it again, I somehow magically revert to the older version (54.0.1).

How can I update to the latest version of Firefox for good and hopefully get past the issue with processes not closing properly in Windows?
