Given the Software showcased over this section I feel a little bit silly showing this but I think this may help someone somewhere.
There were times in which I found myself watching YouTube shorts and longing for a way to interact with them by going to certain timestamp or changing the short's speed (If following a Blender tutorial/demo for example). It is easy to change yourself the URL, but I thought on presenting this facility as a web extension instead.
You can find the code over here (Very simple):

And you can see a demo over here:

P.S. I couldn't afford five dollars to publish it over the Google Web Store.
