Yahoo.com crashing firefox??!?

I'm getting the error

Microsoft Visual C ++ Runtime Library

Runtime Error

Then the path to firefox.exe and a message to contact my administrator.

This is crashing the browser but only when I visit yahoo.com. I had uk.yahoo.com as my homepage so it was crashing as soon as I started it so naturally assumed the program was corupted. So I've reinstalled it 3 times and rebooted also updated my OS today at microsoft.com. I started the program and clicked a bookmark link in the bookmarks toolbar and was able to navigate away from yahoo before it crashed and the browser is having no problem, I'm using it right now. It's possible other sites might crash it too but so far yahoo is the only one and crashes Firefox the instant it loads.

OS WinME
firefox version 1.5.0.4

Any ideas what is causing this and what the fix is?

Clint Eastwood never had this problem.
