Tridactyl is pretty useable, and deceptively powerful, but I might be biased because I wrote a lot of it. Competitors that run on Firefox include: - Vimium-FF - Surfingkeys - Vim-Vixen - Saka Key - Vvvimpulation Further afield, there's: - Vrome - cVim - Qutebrowser Qutebrowser is the only thing that rivals us for capability, but I like Gecko's font rendering too much, and like using other WebExtensions. All of the rest probably beat us in terms of polish. Edit: quite a few of those I mentioned are unmaintained, if you care about that.
