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.

This is perfect. Shorts are so annoying.

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.
