works great, easy to customize.with this addon, it's no longer needed to deal with the problem of the html5 player in firefox. hope it to be maintained for a long time.

Does not work on macOS Ventura;

Followed all the instructions, files are in the correct place, set +x permissions.
PATH is set correctly, both ruby and python3 in brew are working.

But nothing happens... and no errors are logged anywhere :'(

Simple, no ridiculous permissions needed, works great.

Let me randomly mention SponsorBlock script for MPV :) https://github.com/po5/mpv_sponsorblock

An excellent extension. I like using my old 2009 eeebox PC, and this extension allows me to painlessly watch YouTube vids on it! Linux + MPV + yt-dlp + this add-on = old computer's grace saved. Thank you!

This is the greatest Addons EVER!

Simple, beautiful code, and works perfectly.

Does nothing. Just silently fails. No hint what's going wrong.

It's a great extension, but I realized I don't need it because its functionality is implemented by ;v keystroke in Tridactyl.

Seems a really nice addon, unfortunately this doesn't work on my machine.
It seemed weird at the beginning so tried to produce a video on mpv just dropping the link to it, and didn't work, checked some forum and saw I missed the update of youtube-dl. I updated it so it now work dropping link to it.
Tried to check this addon again, but wasn't that lucky, doesn't work anyway :/
Checked the comment, followed the instruction on github and finally works.

Works great.
