This even better than I imagined.

This is absolutely insane!
Really good work.

Nice, but one Feature Request: It would be nice to have an option to have it deactivated by default and only activate it for specific websites.

Been looking for an extension that would allow vim editing in the browser for some time but now it finally exists !
It is a sheer pleasure to use.

By defaut the font will probably appear too big. Sadly the README of the project (https://github.com/glacambre) does not mention how to solve this issue. But on the issue tracker some solutions are proposed (https://github.com/glacambre/firenvim/issues/972)

Since the extension in using neovim in the backend, you should of course have neovim installed.
The `set guifont=my_font:h10` neovim option should solve the issue most of the time. Learn about the `lines` and `colums` neovim options too.

brilliant extension!

Awesome addon! The best way to use neovim from within Firefox and I can do so on demand via a hotkey. Thanks.

Unbelievably, it actually works: vim (with local settings and plugins) in Firefox!

Seems to run fine alongside Vimium, after setting a keybinding to unfocus vim (however text box navigation labels seem to be hidden behind Firenvim). Works perfect on Hacker News but needs a bit of tweaking to play well with web apps like Mattermost.

Impressive!

This is just one of the best extension that I've ever found. Works as expected! Currently the renderer is being rewrite, can't wait to see when it's released!

Fantastic!
