@bronlund tried vivaldi. it is robust, but as a designer visual artist, Opera got the visual and ui correct. Vivaldi seems clunky, though it has rich features.
Opera has to make it a priority to fix one of the main features in any browser -- Tab management. It's there, but buggy. Fix this please. People have been complaining since 2020 on this. This should have been fixed a while ago. The head of development at Opera has dropped the ball.
