Pages with videos loading slowly

Any page on Jezebel with a Gawker video clip on it loads very slowly, to the point that I get the "unresponsive/slow script" pop-up window. I'm running FF on Windows on a Dell, and I clear my cache and cookies constantly, yet nothing seems to change. I also get this on my home laptop, a Dell Inspiron 1521 running Vista and the newest version of Firefox.
