I have been playing around with uBlue’s Bluefin-dx recently, and it’s been a pretty cool change of pace. Rebasing between Gnome and Plasma was pretty amazing (though there was some clean up required.)
However, one thing that I had been missing was sending video links to mpv using the tridactyl extention. Tridactyl adds vim-style keybindings to Firefox making moving around using the keyboard possible. Opening sites, adding bookmarks, and all of the regular things one does when on the internet can be done just from the keyboard.
