Current upgrade version is broken - how can I revert to prior version?

more options

Just now upgraded to Firefox 124.0.2 on Windows 10 - I am not sure what the problem is, but every website (excite Mozilla) is now labelled as "unsafe" by Malwarebytes, and I can no longer log into Gmail using Firefox (other browsers work fine.) How can I revert to a prior version? I could reinstall from a prior version using a old download, but then I lose all my bookmarks, etc.

You can check the connection settings and check for possible issues with a Proxy or VPN service.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a Proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

Try changing DNS over HTTPS (DoH) to "Off" or "Max Protection" and in Connection Settings change "Use system proxy settings" to "No proxy".

Does it still happen in Troubleshoot Mode?

Actually, the problem resolved itself for reasons unknown... I had rebooted multiple times, resetting Malwarebytes, etc. It somehow fixed itself when I logged into the only website that worked (Mozilla). Not sure why.
