what are some good alternatives for enhancer for youtube since it’s not available in firefox addons anymore?

the only features about it that i care about are

  • the volume booster
  • disable autoplay
  • prevent videos loaded in background tabs from automatically playing
  • prevent videos loaded in the foreground tab from automatically playing as well
  • completely stop videos instead of only preventing autoplay
  • pause videos playing in background tabs when a video starts playing in the foreground tab
  • automatically enable youtube’s ‘theater mode’
  • automatically expand the video player
  • use the available space based on the viewport dimensions to expand the video player
  • convert shorts

the adblocker i just use ublock origin for anyway and the dark mode i just use dark reader
