Videos on YouTube lag in fullscreen? Audio is fine, but appears choppy.

Videos are fine in regular small player, but lag in full screen. This problem is only localized to Firefox. Chrome/Safari are fine, however.

My FF is up to date, as well as Shockwave & Flash.

Hello,

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

I forgot to mention, this is also only limited to the Mac OS X partition of my computer. On Firefox on Windows 7 side, they work fine as well.
