One potential cause of this issue is McAfee Site Advisor.

If you do have that extension, and disabling it solves this issue, then this
bug is a duplicate of bug 638657.

Disabling the Site Advisor did indeed solve it.  I assume you will fix this.

No, McAfee has to fix this. Apparently, they're already working on a fix.
