Would love to switch back to Firefox, but the general UX is just too terrible. I also lack the trust that even if they fixed the major issues (or even allowed fixing them yourself) I would be able to rely on things working in the mid-to-long-term. Currently holed up on Vivaldi, where the things you expect out of the box, are in fact working out of the box (vertical tabs, mouse gestures, ...).
