Solving the keyboard accessibility problems the browsers won't solve for us 🙃

This addon is a work in progress, and aims to gradually strip away most of the code in the original vimium. The goal is to be absolutely permissionless, and this addon has already eliminated 80% of the permissions in the original vimium.

This is not without a cost though! Reduced permissions means reduced functionality, so if you're after a very rich vim-like experience in your browser, you may want to stick with the original vimium -- it'll also have more active development.

Vimium-lite, on the other hand is focused on a very specific use case: in page navigation, where tabbing is insufficient.
