Yeah, that’s true.

Edge extension store still has it I think. Use it until Edge removes it as well. Then tell the IT to use Firefox highlighting the importance of adblocking.

PC: Install Firefox. Then install these extensions: Sponsorblock for YouTube, Enhancer for YouTube, uBlock Origins with all the filters turned on except the language filters (you can use them if you wish) and Return YouTube Dislike. Keep uBlock Filters updated by checking for filter updates once a day.

Android: There’s Revanced. I use pre-built apks along with Vanced MicroG from RVX Lite in Telegram.

Android TV: Install SmartTubeNext.

Enjoy.
