|Don't know why previous poster says My Yahoo is suffering a prolonged outage - no evidence of that here.|
"My Yahoo" front page (and all it's links) loads fine on my PC quick as a flash (just tried it), so there's nothing wrong with the website itself - absolutely nothing wrong at their end whatsoever.
Oh, and that's on Firefox too by the way.
So I would check things out with your ISP, see if they are having any issues.
Check your firewall too, may be blocking it, or may be your country authorities are blocking it.
