It's still lagging much behind now "legacy" plugins such as vimperator or pentadactyl, but it's not only the best vim-like plugin there currently is, but it's also pretty good already.

Looks like the best vimperator successor available.

Looking forword to see the evolution of Tridatctyl

Just upgraded to Firefox 58 and found that Vimperator no longer works :(

As I used to be a Pentadactyl user I decided to try Tridactyl. So far it behaves like a developing version of Pentadactyl and although its missing a few things, its pretty much intuitive. No manual needed so far.

So thanks. Nice start and works well with the new super-fast Firefox.

An open source Vimperator replacement? Yes please.
