Firefox with tree-style tabs

1. Go to about:config in Firefox and make sure all of these are enabled/true (as of 136, it appears the only one needed is the first):

toolkit.legacyUserProfileCustomizations.stylesheets
layers.acceleration.force-enabled
gfx.webrender.all
gfx.webrender.enabled
layout.css.backdrop-filter.enabled
svg.context-properties.content.enabled

2. Close Firefox.
3. Set up https://github.com/MrOtherGuy/firefox-csshacks (git method) and add this to userChrome.css:

@import url(chrome/hide_tabs_toolbar_v2.css)
