Unfortunately, I don’t know either. From my understanding, X11 as a whole is supported. Therefore, you should be able to hack your way through this. I suppose the installation instructions for Ubuntu should closely align to what’s required for Debian. So that’s your starting point.
Nice, I’m replying here using Tridactyl for Firefox which is like Vimium so clearly I’m interested.
Does it work well on KDE (so I imagine KWin here) with X11 on Debian 12 (as it’s not mentioned in the listed distributions)?
No harm in compiling it and trying it out
