flash cropping randomly

Help, all flash videos are cropping randomly. Also, when I go full screen, the video doesn't fill up the entire screen like it used to. I still see black frame on all sides. It only happens on Firefox. I tried uninstalling both flash and firefox then reinstalling, but neither solved the issue. It doesn't happen on just youtube, it happens on blip too. You can actually see the black bars move around as it tries to randomly crop the videos. I believe this is purely a Firefox issue because I tried the same videos on Google chrome and didn't run into the same issue.

You need to close and restart Firefox after toggling this setting.

You can check for problems with current Shockwave Flash plugin versions and try this:

Hi, I'm on Windows 7, I don't see a Flash Play in my control panel. Sorry if I forgot to mention that.

Sorry, I'm a dummy, I should have checked those links first.

Ok, I tried that but it still didn't work. There was nothing in there to delete. I tried deleting anyway.

Ok, I got it. Turns out there's two ways to disable hardware acceleration. I was only doing it through Firefox and not through flash itself. I disabled it in flash and it solved the problem. Thanks everyone!
