Screensaver interrupts fullscreen Firefox videos

[mulcahey]

*SIGH* False alarm  This is NOT fixed.

Latest update:

• After starting the computer, it will behave as desired: Staying awake while a video is fullscreen in Firefox. Great!
  
• Then, when I'm done with the video, I exit and walk away. My computer goes to sleep when it reaches the set timeout. Great!
  
• But then, the next time I wake my computer and try to watch a fullscreen video, then the issue comes back: The computer goes to sleep even when the video is fullscreen.
  

Here's what I'm trying now:

• Disable all Firefox add-ons.
  
• completely uninstall Firefox and all its supporting files. Reinstall.
  
• Reinstall pm-utils
  
• Reinstall gnome-power-manager
  
• Restart
  

Testing this now. Fingers crossed

Note: Still odd to me that this ONLY happens with Firefox, and not VLC. Why can my computer detect that VLC is fullscreen, but not the videos that play via Firefox?
