Although, I do not use any browser, but as you added Bromite, you can try Chromium or Bromite. Though, they are heavy on RAM and CPU usage.
What ideally I did was use FOSS Browser, which is nothing but a wrapper kind using the webview functionality. It is not heavy as well. But yes, it is difficult to find a decent working one. I will retry tonight my time, and post my outcome as well once for you.
