Works excellent for me and the negative delay is great

Works perfectly, my bluetooth headphones had a very annoying slight lag. I tried updating drivers and everything, which didn't work—but this extention fixed it.

Works great with TuneBlade to sync YouTube videos. Support for other websites and/or all Firefox Audio would be awesome!

Have some issues with it keeping up with the add-on "SponsorBlock", but it can be used perfectly without it.

Thank you, i suggest adding more advanced number like x,xx ms
