YouTube opens and plays iTunes

[vanderz]

I updated my Mac book yesterday, and since then every time I've tried to watch a YouTube clip on Facebook Or directly from the website. It opens up iTunes and plays music in my iTunes, if i close iTunes i reopens. If i pause iTunes it automatically plays again. Can anyone help me please?
Cheers,
Vanderz

You didn't choose 'Use iTunes for Internet playback' did you? That's the only way I know that that would happen.

What version of the OS, what web browser, what add-ons/plug-ins, etc.

I've just realised i've posted this in the wrong forum.
I have a Macbook Pro 2011.
With OSX 10.6.8


I use Firefox to browse the internet with the following Adons;
Ad Block Plus
Add On Compatibility reporter
Download Helper

And the following plug ins;
iPhotoPhotocast
Java plug in 2
Quicktime
Shockwave Flash
Wacom Pressure plug


I have tried to find the option 'Use iTunes for internet playback' in iTunes & Firefox and cant find it in either.
