The learning curve is there, but once you get the hang of it, you'll be so much more productive!

Great replacement for vimp and penta! Hobbled a bit by the browser API changes, but they're doing their best.

Allowed me to finally switch back to Firefox after the transition to WebExtensions broke Pentadactyl.

MUST have. This extension is pure quality and makes it a joy to browse the web with a keyboard.

As others have noted the limitations placed by the Webapi and the tabopen/open bug that occasionally opens three or more tabs are annoying (the developers themselves are aware of this), but overall this extension has greatly increased my productivity, and navigating links with the keyboard is much easier than using my laptop's crappy trackpad.

I've tried Vim Vixen, Vimium and this, they all have their own set of strengths and weaknesses, but so far Tridactyl is my favorite

Update 24/08/2019: the aforementioned bugs were fixed, tridactyl performs flawlessly.

Loving not having to reach for the mouse almost ever :)

Tridactyl is best replacement for Vimperator currently available. I can't imagine how I'd use browser without it.

Even with very little experience with vim, this addons gives you a free productivity boost, even using a single feature such as pressing 'f' to click buttons or links is very useful.

Can't live without it

This is a fantastic addon that I enjoy so much and install in every firefox browsers I can touch !!

Great extension. It really helped me to navigate faster with a bit of learning

YES! I've been looking for this for YEARS! I only need this one extension and I'm set.

This needs to be expanded and added to baseline firefox. 10/10. never wanna go without it again.

Vim in the browser. Yes.
