Yeah, I've been using it for almost 3 years, I think. Auto playback quality and auto expand the video player are the reasons I use it. YouTube's default media view is too small for my liking, and the theater mode is weird as it doesn't make use of the empty vertical space. The expand mode option of this extension is the perfect one for me.
My extension in Edge:
1) uBlock Origin/Adguard
2) Enhancer for YouTube
3) SponsorBlock for YouTube - Skip Sponsorships
4) McAfee® WebAdvisor when I'm using Microsoft Defender (Which I do most of the time).
Extra: Bitwarden, Bypass Paywalls Clean, Dark Reader, VT4Browsers. These are disabled, and I only enable them when required.
