Seems work fine to me

The ONLY one that works for FF! Even after 5.5 years. You have have restart FF before it works about half the time.

Now, why can't anyone else come up with another version that works ALL the time like they have on Chrome?

FINALLY! AN ADON THAT DOES WHAT IT'S SUPPOSED TO DO! THE USERS WILL TAKE THEIR WEB EXPERIENCE BACK FROM THESE WACK JOBS!

Работает, в отличии от других. По крайней мере на ютубе авто воспроизведение отключает.

Just works.

None of the Youtube extensions have this functionality anymore, but the good news is this works perfectly alongside Enhancer and other extensions [atm].

Thank you very much!

Simply, functionally - The Best! Thanks!

Works perfectly with a few other tweaks!

When I first installed this add-on, it worked perfectly. I recently uninstalled it when YouTube updated it's platform.

This is how I got it to work again and how I stopped YouTube videos from preloading, AT ALL.

1. Get this other add-on YouTube Design Preserver 2.2.0 https://github.com/GuyXY/YouTube-Design-Preserver. Set it to 'Old Layout'

2. In your web browser, go to About:Config. Scroll down to and double click media.autoplay.enabled. This will change the value from 'True' to 'False'. No media on any site is allowed to start playing automatically.

Very useful for quick tab-switching, thank you! :D

It's working for me....

Perfeito.
