@Komposten I'll try your suggestion however, another solution would be to put an option in the Restart Vivaldi to apply the update so thqt the opened tabs are restored.. That would not require setting the Last Session option or to save a session as you indicated but still give the user the option to restore the opened tabs on a update restart. It would be like an autosave of the session but only for the first restart.

@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)

What you want probably is: https://forum.vivaldi.net/topic/32151/tab-groups/31

@Pesala I can save too but I was surprised that it was changed without any mention in changelogs. To reopen session in private window You have to open new private window (Shift + Ctrl + N) and then load session. Oh... Vivaldi also ignores unchecked "Open in new window" option. So... looking at (non-obvious?) implementation it raises questions if this is a bug/regression now or was it bug/regression before. I'd like to hear any official statement.

@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.
