… 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
