We're talking about https://addons.mozilla.org/en-US/firefox/addon/tridactyl-vim...?

One example: it disables the default Ctrl-F search function but its own search function is subpar (no match counts/hlsearch, e.g.) and often clashes with website's built-in search (on Github, e.g.).

It doesn't work on the default newtab either, and changing the default newtab somehow makes opening a new tab slower (that's FF's fault, I guess)…

cool to see you in the wild, for me, it does work out of the box however, some sites will break or have too complex of a navigation, especially with iframes. and will have to swap to a mouse which is a bummer, which I understand is an inherent limitation of the tech, since web is not built today to do that.

solid extension, big fan

I'm not the author, but I recently gave up on Firefox, sadly.

Since I needed to keep around a Chromium anyway, and I already am forced to use one for work, it became simpler to just use solely use a Chromium.

In the process I dropped some extensions.

It's been great.
