Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. Theming experiment for Firefox Quantum and beyond. Export your theme.

Firefox Release June 13, 2017 Version 54.0, first offered to Release channel users on June 13, 2017 Today's release is the first to run Firefox using multiple operating system processes for web page content, making Firefox faster and more stable than ever.
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?
Thank you for your help.
