Anyone else having problems with Yahoo mail?

It's weird. I basically can't open it in Firefox: if I enter mail.yahoo.com in my browser, I get the start page. But if I click on Inbox, nothing happens. I get their little Loading tag on the top of my screen, and eventually it goes away and I'm still on the start page. If I refresh the page, the screen goes white and it goes off to never-never land.

Here's the odd thing: I have no problem accessing my email account through my iPod Touch's web interface. I can't use the Touch's email program because my ISP blocks it somehow for some reason, I heard they were rather profligate with their servers and did a massive lock down. I wonder if they've changed something at my ISP and that's causing my problems.
