Is there a way to disable the "Restart to Keep Using Firefox" page?
I find it incredibly disruptive every time this page comes up and it's never completely capable of restoring my tabs. Is there any way to disable it so that it will instead update when I choose to restart Firefox?
Hamburger menu -> Settings -> General -> "Firefox Updates" -> "check for updates but let you choose to install them"
As for losing open tabs, there're a few different extensions that'll allow you to bookmark all open tabs and throw 'em in a folder. Easy enough to do that before updating, then just delete the folder that's created via the bookmarks manager once you've updated/reopened tabs.
I got bookmarks going back a decade, sometimes I try to visit a random one and find that it no longer exists and I don't remember what it was or why I saved it
When you mentioned it I remembered that of course there is a setting for this.. but when I went to check it just says "Updates disabled by your organisation"
In this case it's a work laptop that has a bunch of "security" things installed on it which prevent me from doing things like ...installing applications I need to do my job. Not sure how Firefox is able to update when it's been explicitly disabled, but I will at least change this setting on my personal computer.
In that case the issue is likely that files on disk are being modified by whatever mechanism your IT uses to push updates to devices. If the program files are modified while Firefox is running then you will unavoidably get this prompt.
I suppose the best you can do is to ask your IT folks to not update programs that are currently running.
