Media volume always set to maximun by default

Whenever I'm on X or Instagram (websites that displays feeds with media), the auto-play video feature sets the volume to the maximum even though I just set the volume to a lower level: like, if I set a Reel or a X (Twitter) video on the feed that was auto-played while scrolling to like 15% volume, the next one will auto-play in the max volume apart from me setting it to low. I already tried to use the Zen Site Volume Manager extension, but it only broke Twitter, blocking me from playing the videos or breaking the page completely.
