Youtube video stuttering, audio fine

I'm a long time Firefox user and this is the first time I've encountered this problem. It involves playing Youtube videos, either embedded in a site or via Youtube itself, I've tried running videos in HTML5, I've tried safe booting Firefox. What happens is in any video I play every so many seconds be it 3 or 15 the video stutters. The sound plays fine. I'm running W7 SP1 x64 fully up to date, latest Nvidia WHQL drivers, up to date Firefox and plugins. All my temp files and caches have been cleared and like I said I've tried running in safemode without plugins. I'm using a late 2013 Retina Macbook Pro in bootcamp. A powerful enough system to run BF4 at 1680x1050 at 45fps on high/ultra, so it should handle a Youtube video fine.

Interesting thing is, Firefox runs fine on my OSX partition and IE11 runs fine on the Windows partition, it is just FF on Windows that is causing me issues and has been for several months now. I've tried finding solutions via google but nothing seems to work and there doesn't seem to be much info aside from clear temp files and disable all plugins. My Windows is very clean and unmodified. It's just a lean install I use for gaming. It's driving me insane and I hope someone can help. I don't know if this effects other bootcamp users.

Hello SCOLANATOR, any luck if you disable Flash protected mode by following the instructions on these pages:

(See this Adobe blog post for technical details about Flash protected mode.)

also disable hardware acceleration in your Flash Player settings. (See this article for more information on using the Flash plugin in Firefox).

  1. Go to this Adobe Flash Player Help page.
  2. Right-click on the Flash Player logo on that page.
  3. Click on Settings in the context menu. The Adobe Flash Player Settings screen will open.
  4. Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel.

    The image "fpSettings1.PNG" does not exist.
  5. Remove the check mark from Enable hardware acceleration.
  6. Click Close to close the Adobe Flash Player Settings Window.
  7. Restart Firefox.

This Flash Player Help - Display Settings page has more information on Flash Player hardware acceleration, if you're interested.

thank you

You can also try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
