Have been avoiding to upgrade from Firefox ESR because Vimperator no longer works in newer Firefox versions. Finally tried the latest Firefox with this extension today, and wow. It isn't quite there yet but pretty dang close to what I need. Vimperator was the only reason I used Firefox in the first place, and this extension is the only reason I'd use post-ESR Firefox. Thanks for making Firefox usable again!

Nice!

I really appreciate your work! In fact, I just switched from firefox esr 52 to quantum 60 and I was in a loss when I found vimperator is no longer supported in newest versions of firefox. Finally I got a satisfactory alternative from your kind work. Thanks a lot! This is the reason why I use firefox (Vimium is just not that costomized!). Pitifully I do not have a valid Paypal account (not properlly supported in China), but please accept my simcere gratitute to you!

I used to help maintain Vimperator which has now stopped development due to Firefox addon API deprecation. Tridactyl however has proven to be a worthy successor! The user experience is great, and long time users of similar addons such as Pentadactyl should feel at home. Due to the nature of changes in WebExtensions and its earlier and current limitations I'm really excited to see it come this far!

Importantly, the project also has great development momentum with lots of features being added or bugs being fixed all the time. This is truly a breath of fresh air in the enthusiast community of power users looking to vimify or otherwise enhance their browser experience, which for some time has been stale with the foreshadowing of the deprecation of XUL/XPCOM and ultimately the need to port or discard lots and lots of old code.

Remember to check out #tridactyl on the many platforms its available, including the ever present Freenode. More information can be found in the README on their GitHub project.

Excellent addon. Makes firefox useable!

The reason I use Firefox!

This add-on keeps getting better and better. Coming from Vimperator I was missing a lot of functionality at the start and I was switching between different replacements like Vim Vixen. But over time more and more functionality was added back in and I settled on Tridactyl. I almost wet myself when CTRL + ^(6) and . started working again. Obviously it's not always as smooth as Vimperator, due to it being a content script, but it gets me most of the way there. Keep up the good work!

This is the closest thing to Pentadctyl you will find in the new WebExtensions world. It's gotten good enough that I've switched off of Pale Moon (a FF fork) to Firefox and I'm relatively happy so far.

I've been a long time pentadactyl user and like other reviewers here have been evaluating a few alternatives to replace it . So far it seems like tridactyl is the only current one that approaches and has the best potential in trying to provide a pentadactyl/vimperator experience.

Being used to the maturity of pentadactyl, using tridactyl does leave me feeling a bit disabled

- tridactyl sometimes stop working on some pages and I have to switch tabs and back to get it working again
- mapping like 'gh/GH' appear to be documented but do not seem to work.
- things feel slower, e.g. my muscle memory from pentadactyl has a T + Enter to open a newtab but in tridactyl opening the commandline takes about half a second - making a few things no-ops and I have to attempt again albeit slower. :)
- tab-completion at the command line is missing. I hope this gets added.
- searching still uses the firefox native search interface (i.e. `ctrl-f`) but a feature to support this appears to be under development.
- some keybindings are different from pentadactyl - e.g. `yy` as opposed to `y` to yank the url - arguably tridactyl is doing the right thing but it does mean some investment in unlearning/remapping things.
- a lot of my custom plugins for pentdactyl don't work but as javascript support improves, things could be ported over but the docs/examples on this front are few and far between.

tridactyl is still young but has an active community/code-base and I'm sure most of my pains will go away in time. So far it looks like this is the contender I will stick with.

Here's hoping that this will become a worthy successor to Vimperator

Fantastic addon, very good work.

Sometimes, when on gmail, I get this error:

"# Error: # Tridactyl's native messenger doesn't support your operating system, yet."

This extension is awesome. For a while I was using the extended release version of Firefox so that I could keep using Vimperator, but Tridactyl has reached the point where that's no longer necessary. Also it's currently very actively developed, and has gotten a lot better in the last few weeks even. Great work!

I was using one of the post WebExtension vim addons before I heard of this one. Very impressed!
Best Firefox vim addon at the moment, keep up the great work developers!

4 stars because this is just a work in progress, but has the most potential of any.

I would really like to open links in container tabs, but this could be an API limitation.

Great addon! One thing that could be improved is the selection of keys for multi-key shortcuts which should ideally use keys that are next to each other.

EDIT: Thanks for the quick reply! I guess I was a bit unclear with what I meant. I wasn't referring to the shortcuts for commands (I'm actually very happy with those) but the little hint tags that show up when pressing f/F. My suggestion here would be to prioritize simple combinations (double keys, nearby keys) based on a selected keyboard layout (e.g. qq, kk, qw, kl, ...) instead of just incrementally exhausting the 'hintchars' pool.
