Great feature philosophy. I did not expect this extension to come out, nor did I expect it to completely replace the rather broken vimium that I had to suffer through until now.

Note that this does not (and will never) have feature parity with vimperator/pentadactyl. Honestly, that's a good thing: Both of those extensions were badly broken and decimated browser performance. The only issues that I have with this addon are strictly Firefox's limitations on webextensions (the most egregious of which is the inability to use this addon when it's on a 'system' page like a new tab.
