Yup, I'm getting this behaviour too: Using Firefox, "connection was reset".

I've turned off the facebook thing, but it doesn't make a difference. I've been experiencing this behaviour on and off for over a month now. I've got 2 different ISPs at home here in Canada and I've seen it while traveling in the US too going through the hotel's ISP. I've also only noticed it with Flyertalk.

Right now, pages seems to load fine then die when displaying googleleads.g.doubleclick.net/.... IE and Chrome are much better, but I've still had the odd error.
