Flash and Silverlight are very slow in FF but not in Chrome or Safari in identical situations.

This is particularly noticeable with Netflix, Youtube, Vimeo and other flash/silverlight sites.

Firefox will load everything fine, but will have stuttered playback, even with buffering completed. The exact same page in Chrome or Safari will play completely smoothly even before buffering is done or even with Firefox running the same page in the background.

This happened

Every time Firefox opened

== Since I got a new Macbook Pro.
