I hope this is temporary, as I never seen software roll out updates as aggressive as this. Firefox refused to load new tabs until I completely closed it. It interrupted everything I was doing and I had to log back into everything afterward (I mostly use private browsing). Not much of a "background" update. Even the infamous Windows 7 Update allowed you to emergency delay the restart when the dialog box appeared.
I've been a firefox user for over 20 years and this might force me to use an alternative in a way no other software has. It happens on all of my computers.
@fuopy I had this too, turned it off - it's in settings
@mdiluz Awesome!! Thanks for sharing. Hope this fixes it. I really wouldn't want to switch to the end-of-web browser family, but I have to use software that doesn't sabotage my work. Hopefully mozilla quickly makes this a default setting or fixes it. I'm sure there are others like me who hit this.
@fuopy *are* there any alternatives?
@kepeken @fuopy Vivaldi. And to my knowledge, only Vivaldi.

@yora @fuopy i haven't found whether vivaldi will support manifest v2 independently of Google long-term, but from Reddit it appears that their built-in adblock falls behind youtube updates too often (ublock origin doesn't)

at this point it seems like our best bet would be firefox forks like waterfox or librewolf?

@fuopy

I've been getting sooooo tired of firefox doing this as well especially at work. It's so annoying it actually makes me want to go back to chromium

@fuopy didn't they get rid of this recently? Maybe I am misremembering.

Whatever the case, this has been a thing for years and is more or less a technical limitation. If you update Firefox on Linux while running it, it could theoretically start new processes with different libraries as the already running processes. The consequences are pretty much unpredictable (probably resulting in a crash most of the time). Of course there are chances of it just working fine, but the Firefox developers probably don't want to take that risk. Especially to avoid people reporting non-existent bugs.

@fuopy been on librewolf for a few years now and no regrets so far. Its a very minimal fork, and you can still re-enable things if you want them at the cost of some privacy. They diverge with Firefox on a lot of unfriendly default behaviours like this as well.
