I had been very impressed with the ethos of those behind @Vivaldi for a while, and have gone back and forth between that and Firefox, but Mozilla have finally done too much to push many of us away - for good this time, it seems, for me: I now have Vivaldi on all my main devices and I love it. When it comes to web browsers, I am what you'd probably call a "power user" and Vivaldi is certainly geared up for that!
