I have recently returned to Firefox after a long absence. The reason I stopped using it in the first place is that every time I got all the add-ons that I wanted, there would be a new update and I'd lose some or all of them and I wasn't interested in having some/all of my useful functions disabled until who knows when or forever. I've currently got automatic updates turned off, and that is where they will stay unless I can verify that the add-ons are backwards compatible or there is an update for the add-on. Is there a way to see what current add-ons will be disabled with an update?
