Vivaldi has some amazing features that I wish other browsers would catch up on. Unfortunately it’s really buggy. Crashes with no recourse to recover your tabs. That’s a deal breaker and I dealt with that a fair number of times. Then I decided I’d use their workspaces feature to try and avoid losing all my tabs. Great plan, worked until all my fucking workspaces got deleted too. For every good feature Vivaldi has, it has several game breaking bugs.
