I don't have strong opinions but I've been happily using Vimium for years

Vimium-C is more advanced and works better if English is not your only keyboard layout.
And you are ok with the whole China owns Taiwan thing. (At bottom of git repo)
I have no idea what's in their GitHub repository, also I don't know what's the deal with China or Taiwan. I found this extension in Addons.Mozilla.Org and it gets the job done, so that's what I'm using.
So you went out of your way to find something on a GitHub page of the developer of the extension I use and took this screenshot, for what? To prove me this extension is worse than others? I'm not getting your point.
If you don't like it or political views of developers are important part of your process of choosing software, nobody is forcing you to use that extension. I suggested whatever I use because it fits my needs, no need to tell me if I'm right or wrong in using the software I choose.
I was citing my source. I don't have any idea what matters to you in your choice of software, but if this did matter, I wanted you to have the information to make the best choices for yourself.
I really like tridactyl, but I haven't tried any alternatives yet - following this post with interest :))
Same I just went with Tridactyl without a particular reason. Though their native messaging part, where you can execute stuff like your editor with a keybinding is a nice addon that others don't have.
Tridactyl is the best. It is supporting editing textarea with vim/emacs
I like surfingkeys. Haven't tried others though.
Tridactyl or Vim Vixen are the best if you want to get out the gate with minimal customization.
If you want to spend several hours finetuning use vimmium.
If you want to support the people's republic of china, use vimmium c
