Great

Best thing since invention of you tube

Big thanks for a solution to a problem that shouldn't exist!!

very well written :)

omg I just found this a couple days ago and it is the freaking BEST!! I love my youtube music playlist as I work from home and I was running to restart it every 40 min for hours...no more! thank you so much! huge gratitude!

Used to be able to get around the pesky confirmation until 2 days ago when it stopped working completely, earlier it was an awesome addon, but atm it's not doing anything, probably due to some update on youtubes end.
EDIT: Been using YuoTube NonStop for about 5 months, and worked flawlessly until now, so im pretty sure YouTube updated something to make sure YouTube NonStop no longer works.
EDIT2: Now it sometimes work, and sometimes not, quite confusing.
EDIT3: Now it's back to working every time, seems like the days it wasn't working was when Youtube was rolling out some new updates like how you now can preview a vid by merely hovering over it.
