@edwardp: That was the correct place to post your issue. If you had no replies, it would be because no one who read your comment felt like they had an answer for you. The forum is just other users for the most part, and to get a response, someone who read it would have to feel they had something meaningful to tell you. NOW - there was another comment just today, that someone could not start the browser after update on Linux (not Fedora). https://forum.vivaldi.net/topic/14788/new-1-8-770-9-does-not-start?page=1 That generated a long discussion and an eventual solution. I don't know if anyone involved in that discussion would have help for you, but you can post there and see if anyone has a reply.
