Why is all text grey in Firefox?

[slicendice]

I'm having a problem with Firefox whereby all web pages have a white background and all text is grey (regardless of the colour it should actually be). Images seem to show correctly but that's about it.

I was originally on v3 but I've just upgraded to v4 and I have exactly the same problem.

Can anyone suggest a reason why this might be happening and how to fix it?

Thanks

Sorry, ignore me...just found that text colour was set to Grey in Tools => Options => Content => Colours.

Now fixed!!!
