I did what you suggested and in typical Microsoft fashion, it only partially removed an infected file.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

If this hasn't helped then also delete possible addons.json and addons.sqlite files.

You can also check for problems with preferences.

In case Firefox performed an automatic reset, could you check for desktop for an Old Firefox Data folder?

As a solution you can try this out delete your Firefox profile and uninstalled the browser cleanup any antivirus feature and then Install Firefox again.
