It's a great addon but since last update i can't download anything from Firefox. I've done troubleshooting and it's definetely this addon. Please fix :(!

No longer works on my browser. I'll change my rating once this is fixed.

The extension works! Not sure if it poses a privacy risk though.

Actually useful extension that re-adds one of Youtube's greatest features. Sad to see Google remove it but this works!

BEST!
