I just really despise using a mouse and fiddling around with high-friction window activities. I typically have very direct goals and should be able to achieve them with a keystroke or two. 95% of that can be achieved in terminal+tmux+vim. For everything else, I expect the rest of my environment to work as close to tmux+vim as possible. is that too much to ask?! lol

Yep, I use qutebrowser. I like it for the obvious reasons you can guess from my above comment.
Lack of extensions is a bit of a problem for some things wrt nostr, bitcoin, etc. but for most everyday browsing it is excellent.
