Hot tip: To remove AI summaries from Youtube.

What you will need: Firefox and the Ublock Origins extension (Make sure your verify its the legit extension)

Go to your "filters" in settings.

Add these scripts:
www.youtube.com###expandable-metadata
www.youtube.com###flexible-item-buttons

I might put together a megathread to making the internet usable again from scripts others have written or I have found.
