When opening a page including a Flash video player, such as YouTube or Pajamas Media, the player will not load. There is no error message; simply a blank white area where the player normally appears. 

This is a problem with this nightly build only. The same videos which will not load in this build work normally with the nightly 3.5b5 (Gecko 1.9.1) and Chrome. 

Reproducible: Always

Steps to Reproduce:
1.Open a page which includes a Flash video player.
2.
3.
Actual Results:  
The page loads normally, except that the player never appears.

Expected Results:  
The player should have appeared and the video should have played.

Besides my example YouTube URL <http://www.youtube.com/watch?v=o9Ak7Tk9B3s>, here is another from Pajamas TV: <http://tinyurl.com/ram4oh>
Both of these load and play normally in the latest nightly Shiretoko 3.5b5 (Gecko 1.9.1), as well as in Chrome.
