… i was supposed to be restarting after updating Firefox???

Just restarting Firefox, not the entire system.

Which doesn’t really matter for 99.99% of users that are sane and only use a couple windows and tabs at a time. Saving things they aren’t actively using anymore as bookmarks and using the browsing history for anything they closed previously but need again.

For the 0.01% of insane but vocal users that never close tabs and/or keep dozens of windows open, that’s a big deal.

ah, then yeah I just have “restore previous tabs” selected and restart the app, no biggie

Yeah that’s what those of us that are sane experience, but that only works for the last window closed.
