Facebook applications not loading

[Markeh]

Tried loading Restaurant City or Street Racing on Facebook, and Firefox returns this error:

I can't find anything to do with enabling or disabling cookies in settings. This is REALLY irritating me.

Also, randomly, one or 2 people's profiles refuse to load, like they've been deleted and have never existed.

I am using FF 3.5.3 and IE8 on Vista Premium, on a 2 week old PC. Plus, Safari on my iPod has come up with this error:

Safari cannot open the page beccause too many redirects occured.

Any ideas?

BTW, this now happens on EVERY APP.
