Once again I have to let people know about glide[0], fork of Firefox. I know a lot of people here like keyboard-driven and scriptable software, and glide shines at both. Keyboard control in it is so so much better than the extensions for Chrome or Firefox, and I'm quite happy how easily the API allows me do my own customizations. (as an example when I open HN in new tab with my bind ,sn , if I already have HN front page open it will refresh it, focus it and move it to the tab index where new tab would otherwise have opened. Really simple stuff in glide, not so much in others)
