So I've been having this problem for awhile now, I've tried searching everywhere i can think of and still have not found an answer. When im watching a flash video in firefox, sometimes it will randomly exit fullscreen. This is extremely annoying when im trying to watch a movie. Sometimes it doesnt happen at all, sometimes it happens every minute or so. I was thinking maybe a program is kicking it out of fullscreen but if so i have yet to figure out which one. If anyone has encountered this before and knows how to fix it, i would really appreciate some help. If you have any ideas of things to try im willing to work on this as it is VERY annoying. Thanks in advance.
