YTBShortBlocker Autor: Sohukia

This extension just remove the pannel from the DOM so it is no longer visible. Anyway, you can still access the Youtube Short by going to the address https://www.youtube.com/shorts
It should work but do not hesitate to send me an email at sohukia@duck.com if you experience any issues.
