I think I’ll back up my bookmarks to be on the safe side. Hopefully it doesn’t impact me because I’ll never sign up for a Firefox account, or for any other browser for that matter. On edit: no problems updating.
But I’m guessing this is a common problem, as they’re already pushing a 78.0.1 update.
I don’t do auto-update on my browser, I do it manually through Chocolatey. Just in case issues like this come up and I’m ready to deal with any possible clusterfucks. I make it a policy to disable auto-updates whenever possible… which is one of the many things that pisses me off about Windows 10. Though I found away to get around that one too (see my previous comments about W10 Privacy)
