Since early February, Firefox users may have tripped on a Google AdSense security error. The error reads:

Security Error: Content at may not load data from

It happens on some configurations of Firefox, where the security prompt seems to be warning you that content from a third party is loading on this web page.

There are threads as far back as February with this issue, specifically from Google AdSense Help. A newer thread at WebmasterWorld has more discussion around the security error.

I honestly don't think this is a Google specific issue. It seems to be a setting that warns surfers of third party content showing up on a web page. has an article that describes how you can "fix" this security prompt from showing. But in the AdSense case, it might not work.
