Well, with all the news around Firefox lately, I thought about giving #gnome Web (#epiphany) another try. For several years now, it's one of my fallback browsers if I can't or don't want to use Firefox. But now I wanted to replicate my usual tab setup.
It didn't go so well. It already failed at getting the #KeePassXC Browser extension to work. And I don't see myself again switching between the password manager and the browser, copying usernames and passwords.
So, it's either #Zen Browser (based on Firefox) or #Vivaldi, then.
