On Linux I used https://en.wikipedia.org/wiki/Conkeror for its speed. On Windows Ive been mostly in Opera but frequent crashes and problems with many Google apps made me switch to Chrome again.I've loved Braves privacy and Operas/Firefoxs ability to send tabs directly to my phone, but not so much that I can stand instability.
tl;dr: Im back in Chrome and not too happy about it.
