I actually finally just switched to Chrome (I'm a long time Firefox user, all the way back to when it was called Firebird), because of this issue:

Windows Defender flags things in the Firefox cache as a Trojan. It probably isn't, and it could also have something to do with uBlock Origin, but until that is resolved (I'm keeping an eye on the above link) I can't risk it.

i haven't seen that at all. Perhaps a refresh, clean install after deleting the hidden app folders in home?

I haven't done a re-install, but deleting the cache folder alone doesn't make it go away. Starting Firefox re-creates the folder obviously, and Defender gets triggered again.
