Why can't the devs have it update in the background or on next startup? I was in the middle of my work when I got this. Now I need to close everything and go through all the logins and 2FA again. ๐ก
Chrome is much better at this, hands down. It has never interrupted me the way Firefox does during updates.
If that happens, you should recover from a snapshot... I never experienced this unless the profile folder was damaged or lost.
