When I click on an item to read on the yahoo! homepage, I am frequently seeing this msg: Sorry, Bad Request. Your browser sent a request that this server could not understand.

Size of a request header field exceeds server limit. There is more, but I didn't capture it. I will have to exit firefox and then use internet explorer to read the item. This began last week.
