Chrome works wonderfully with 1Password, but doesn't support extensions. You can block ads, but it if you root.
Firefox has great extension support, but doesn't work well with 1Password.
I just tried out the new Samsung browser, which is close! However, I have everything to select an entry several times for it to actually fill properly. And, 1P can't detect the current site.
Given the security issues with ads (last time I disabled adblockers, I got 3 phishing style ads pretending to be Google in a day), it'd be great to not have to choose. So, any suggestions on a browser that works well for both cases?
