Does not work with Firefox for Android, though it is able to be added to Firefox for Android. It doesn't actually block shorts videos, just the "shorts" tab. Doesnt seem to be updated.

I've been looking for this!,shorts r annoying and I don't like to watch it nor seeing their thumbnails.. thank you very much!!

genunily allowed me to be a lot more productive with my time

For me its just perfect. You can still watch the short videos, but they dont appear as shorts anymore. Now its just like a normal video. The best Thing is that it prevents you from scrolling.

Thank you very much for such a great extension, Lenna

Simple and effective extension that blocks YouTube Shorts right after installation, with no extra setup needed. Clean, lightweight, and doesn’t interfere with normal video watching. Great for staying focused and avoiding endless short-form distractions. A very practical tool overall.
