Streaming Videos Turn Green

Question

Hi!
I didn't find any solutions to this, but I was wondering if someone here knows how to fix this problem?
When I watch streaming clips in Firefox with Quicktime, my video screen turns green, but the sound still continues. This happens if my mouse moves over the video screen, if other applications cover it for a second or if I switch between tabs.
Any help is very much appreciated!
