Hey, thanks for the reviewing! I would like to do all of this, but I get a "Sorry, we couldn't load your WebExtension." error and the MDN docs show 404 on the pages... GitHub says that it's been fixed but it hasn't & Wayback Machine didn't capture a working version. I've fixed the background (it was too small) and made it darker in v2.0, but everything else (like the white menu background) don't show up in the Mozilla Theme Generator as options.
