This sadly no longer works but it was great for a while

Was nice while it lasted but as others have said it's broken right now, and also totally broke volume control on shorts so I had to uninstall.
Since shorts natively have a progress/scrub bar now this is less required but I do miss the arrow key shortcuts for +-5sec skipping.

Most features in this stopped working correctly as both Youtube and Firefox updated. This addon has not been updated to address these issues.

Stopped working with FF 137.0.2

Finally commonsense added to YT Shorts.

From my experience this has a really bad memory leak issue

Working as intended so far

Usually switches to next short, sometimes don't. And when next is an ad, it switches the audio but keeps the paused end of previous short. I have uBlock too, maybe they don't work together.

Progress bar still NOT working

Very cool
