Cross-site scripting warnings?

I've been seeing a couple of warnings from Firefox lately. I just had to re-install it so I don't have NoScript on, but plain old Firefox is telling me that "Firefox prevented this page from automatically redirecting to another page."



I generally read the forum by selecting "New posts" and then opening a new tab for each thread I want to read. I'm getting the warning on about half the therads. I can reinstall NoScript and post more specific stuff from the console if that would be useful.
