Hello,

I am responsible for developing a html5 game in which m4v videos are played and the user must guess which movie the clip is from. Everything worked fine until Firefox 11 Mac was released (it works in Windows).

The streams also work when FireFox Mac is started in Safe Mode.

I should also mention that the audio streams but not the video outside of safe mode.

It isn't a problem with my plug ins, I've tried disabling them all outside of safe mode and it still wont stream.

Any suggestions?

I can't post the URL.

Safe mode disables the extensions (Tools > Add-ons > Extensions), but not the plugins.

Is there any JavaScript involved?

In Firefox 4 and later, Safe mode disables extensions and disables hardware acceleration and disables the JIT compiler.

Try to disable hardware acceleration.

Thankyou so much. It was the hardware acceleration thing. Going to have to put it in a FAQ panel.
