I'm having the same exact problem with Firefox 3.6.8 (aside from many other bugs), same homepage, same widget (NY Times). Only, I'm running OS 10.4.11 on a Mac.

I forgot to add, it's an intermittent problem; it comes and goes, mostly "goes."

Yep - saw this before with a previous FF update, then it was gone until 3.6.8 and now it's back. The NYT widget fails more often than not. And it seems ok on Mac, but not on Win 7.
