perc 30 for firefox

replaces the tab bar with a custom vertical tab tree implementation, adds true splitscreen, various other ui tweaks

• get fx-autoconfig from here
• download adderall.uc.js into your profile/chrome/JS folder
• clear startup cache and restart
• install tabtree from here. i will make the gh repo for this later
• [optional] install the vimium addon. you are supposed to use this for back/forward/reload buttons, then make sure you add this css into your userChrome.css

btw you can't use this with floorp. just don't use floorp in general actually
