I'm looking for a #firefox #extension to play/pause two videos simultaneously, each being in a different tab.
I sometimes watch movies from *unofficial* streaming sites with friends who want dubbing. The dubbed version has often poor quality, but it's easy to find hight quality version with english audio. What I do is to play both, mute the english one and manually sync them. That takes time, and pausing is pain as I have to sync them again afterwards.
Boost appreciated
