Yahoo! all messed up in firefox.

Hey guys, I have a very interesting problem that I can't figure out for the life of me.

I've had no problems for months with firefix, but for some reason starting last night, yahoo shows up as a very messed up looking site in firefox. All other browsers it works fine with, but not with firefox.

Whats going on and how can I fix this? Any ideas?

Here's a screen by the way of what it looks like:

Thanks for all the help in advance guys!

I don't have a Mac, but I see that from time to time in windows, usually when a page loads slowly or the site is having server issues. You can try refreshing, or just come back later when things have been sorted out on their end
