security-certificate

Toolbarqueries.google.com Incorrect Security Certificate.

Every once in a while, ever since the last Firefox update, I have been getting a security certificate mismatch error from Firefox. Not sure if this is an issue with Firefox or with Google or with the Google toolbar. I am also not sure why it occurs randomly. And since it happens when I open a new tab and not with searches from the Google toolbar, why it occurs at all. And if Google is only supposed to be spying on me when I search since I have the "Send usage statistics to Google" box unchecked, does this mean that this option is not really an option?
