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. 😡
Chrome is much better at this, hands down. It has never interrupted me the way Firefox does during updates.
I see it under linux after updating Firefox through the package manager. Maybe OP’s distro auto updates packages?
