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.
For anyone who is still confused about what causes this: Firefox launches copies of itself when creating new website instances (usually when loading a website that has not already been loaded). Because of this, if it is updated in the background (through any means; I usually see this after a manual system update), Firefox has to restart when you try and load a new site because it cannot create any compatible copies of itself, since the old version is the one that is still running and the copies would use the new (updated) version.
The solution is to only update when Firefox is closed, or restart it when it asks.
IME it happens when I open a new tab.
Yep; sometimes I will be able to do a search and then when I try to click on a result it has me restart.
The solution is not a solution but is good enough.
