Every day I go through my YT subscriptions list and open every new video in a new tab (CMD + click). Then I play the 1st new video, close the tab, switch to the next tab..
Several weeks ago all videos were using the HTML5 player (not the Flash player).
The HTML5 player sucks!
1.) It auto-plays the video. This sucks when opening 10 – 30 videos at once!
2.) It's slow
3.) I don't want it
http://www.youtube.com/html5 says HTML5 beta is not enabled.
How to get rid of it?
I already installed The YouTube Center Greasemonkey Script, this gives me back the Flash player, but auto play still isn't disabled correctly:
When opening these 10-30 videos from my subscription list, some of them auto play for several seconds before they stop.
WHAT TO DO ?? đ
Using Chrome Version 30.0.1599.101
E.g. this video plays for 0-5 seconds before it switches to the Flash player (then it stops playing): http://www.youtube.com/watch?v=KGA57mMI0J8
