I kinda-frequently find myself in the situation that Firefox already downloaded an update, but some time passes before I bit the bullet of actually restarting it. So a new update has appeared - but I can't download it until I restart. So I will have to restart, reload session, download new update, restart again, reload session again. So it would be great to be able to tell Firefox to forget about the already-downloaded update and just download the latest one. Can this be done? (The reason why I delay restarting is because I have an unhealthy amount of tabs open, typically with many things in flight; so restarting makes me lose those things, plus there's always the possibility of some trouble while restoring all the tabs) FWIW I'm in the Beta channel.
