I use Helium.

I prefer Firefox as it is still the only feasible non-chromium alternative.

I have been a firefox user for more than two decades - since it was called Pheonix and later Firebird.

Firefox — Everyone loves to play armchair CEO and dictate the ills of the company. But I think they do so because Firefox is largely the only independent rendering engine and with Google's foothold on browsers (to protect their ad revenue) I'm nervous about the future of Blink. Independent players are always good for competition.

Anything that can run uBO proper. So, Firefox.
