It saddens me a bit it that there isn't a bigger community around third party Firefox UIs. I've messed around with repacking omnni.ja (which is a freaking hell on NixOS) but I'm too crap at front-end to make use of it. I'd like qutebrowser but with Firefox plugins (Tridactyl isn't good enough to feel native).
