Yahoo mail? Not quite
It seems Yahoo are in the process of revamping their online e-mail application. The only thing is, it’s not ready yet. And they appeared to have screwed up the old version as well.
A clearing of cached files failed to provide any relief. IE6, FF1.5 or NS7.2, all broken.
What did it eventually turn out to be? My employer’s corporate firewall. Well done us! I know most of our ~10K on-site clients use web based mail, I wonder how many of them use Yahoo! mail. Oh well.
