Can confirm it's not OSX specific, also occurs in Windows 7.  Simply let any movie run for ~1 hour and Firefox will crash.  Hangs can be recovered from *sometimes* but often lead to a second hang shortly after that is unrecoverable - when this occurs Firefox consistently shows 1.7gb of RAM usage on my system.  Either way the plugin container is failing to do it's job to protect the browser from crashing when Silverlight is in use.

Is this still reproducible with latest Firefox releases?
