I've used the vimium for chrome, vimfx for firefox and they both have similar problems:

1) Impossible to navigate some sites 2) Slows down the browser to a crawl over time

Generally, not a usable long-term solution

I use Vimperator, never noticed any slowdown effect. Why would that even happen?

It's true that some sites are harder to navigate, though.

Vimperator is the king among Vim-like keyboard shortcut enabler extensions in browsers, sadly it may not work in the future versions of Firefox because Firefox is transitioning from highly free but less safe/performing XUL based extensions to a safer but limited WebExtension model. It is very fast and smooth with lots of features.

RIP vimperator :(

I used vimperator and experienced crazy slowdown on Firefox in both OSX and Ubuntu. This happens after you browse for a while. Wasn't sure why initially. Things improved dramatically after reinstalling the addon. But I had to do it frequently so it wasn't worth it.

I think it's because things are saved in history for a long time or history chain of sites in a tab is very long.

Edit: Only extension that is vim-like that hasn't let me down is cvim for chromium/chrome.
