You either have Firefox or Chromium-based browsers...

There's Falkon, AngelFish, Lynx... You should be more specific on what you need.

All in all, I would recommend you to stick with Firefox

Please don't use Ungoogled Chromium instead of Firefox. The Blink monoculture doesn't need to get even worse.

I totally agree!!! Mozilla saved (literally!) the internet once already. They deserve our support!
