Hi everyone, just figured out problems with YouTube-videos playing in a facebook timeline and scrolling down, until the "player" is not visible anymore. Suddenly when the player is out of sight it will stop playing and after a scroll-up the player is just filled out completely gray without any option keys. It can be reproduced on any fb-page whenever a youtube-video is played and is scrolled out of sight. Another problem i found is the upload of more than about 10 pictures at the same time, the upload stops and won't finish, even after 30 mins of waiting-nothing happened. My question is now: can anyone confirm/reproduce this? Tried a clean install of OS X 10.8 with and without every update, it makes no difference.
