@shadess haha that would be funny - when you see something from 2 days back...would be confusing as hell But then a weird thing happened - and I remember it happening before too - after like an hour, I see another V instance in the background, and it popped right back ! The old session which I wanted!! I had been wanting to update the forum but forgot to. I doubt V can do much if session handling is done by the Chromium engine and doesnt expose any APIs for it And the best part - for me - fortunately it only happens on F12 for Dev Tools (once in 10 times)....gonna remove that key if I can lol Done - now must just remember the odd shortcut Ctrl+Shift+I which seems to be the Chrome default (at least V lets us change (some of) the darn weird shortcuts)

@ondrej-ulman Vivaldi already does save the current session on closing. Set the startup setting to "Last Session." If Vivaldi crashes, or if some processes are running in the background, the session won't be saved. If you encounter this problem, use Task Manager to end all Vivaldi tasks, then the session should again save OK.

@AltCode [This request is about one year old.] I downloaded some random older build (the first one I found was 1.11.917.35), tested this and nope... it didn't work (so this request was valid). I also tested it on some newer builds - and surprisingly it works. Maybe it was a bug / regression one year ago?... But I don't remember anything about this mentioned about this in changelogs. Oh... I listed Vivaldi restart just to be sure that we have "clean" state. So... to sum up: It looks like implemented. It's great but also strange that nobody pointed it out... I have no idea if it was intended to work as it works now. Restoring session from private window in private window is tricky and user unfriendly. I'd be happy if any developer could comment this workflow / behaviour.

@dypsis @waterfire Also switched from FF to Vivaldi. I also use Session Buddy (https://chrome.google.com/webstore/detail/session-buddy/edacconmaakjimmfgnblocblbcdcpbko) as my session manager. Not perfect but a good alternative IMHO.

@novaviper Unfortunately, turning extensions off may not be enough. As a test, rename your Vivaldi Default folder and see if it still crashes for you with a fresh profile (you can always rename back after testing) see https://forum.vivaldi.net/topic/10388/refreshing-or-cleaning-your-profile

Restoring sessions seems to be buggy. You should always save your browser session to make sure ('save open tabs as session'). If a third party session manager does the job better in your opinion, stick with that.
