alternatives to enhancer for youtube?

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
