it works pretty good but frequently i'll pause a you tube video and then come back an hour or so later and when i press play again it starts but then immediately pauses. this doesn't occur with other plugins alike... it does work on a complete different browser lets say you opened fire fox opened youtube then played a video then minimized it opened a whole new firefox window and went shopping opened 4 tabs and then decide you want to pause the music it did work to pause from that window while youtube was minimized so that much was awsome i just wish it worked while everything was minimized.
