this one is stable and useful

It's amazing.
I'm a vim hard fan and use it everywhere from coding(vs vim addon) to my OS window manager (i3) and now i can use it in my browser.
It's only problem is that editing text boxes are not vim like. but except that it's awesome.

great tool

Awesome. I've been using qutebrower but it's crashing all the time so I reluctantly returned to Firefox and I stumbled on this plugin. What a relief.

I love this extension.

Very useful! Especially when you open up to 40 tabs (I always do that btw), much easier to navigate through tabs, and save me when my touch pad got broken.

Отличный функционал, но мне постоянно приходится его переустанавливать, ибо он просто отказывается работать. Я пока не могу нормально им пользоваться, ибо каждый час его переустанавливать, извините.
