Stephan, in Firefox’s Tools menu, you can find the Add-ons manager where you can disable any Firefox extensions. if you disable the Google Toolbar, do you still see this same message?

Sorry, I forgot to add, I don’t think this is a Firefox problem. I suspect that this is the Google Toolbar querying a Google server for page data, possibly to display the PageRank or something like that.

Yes, I am pretty sure it’s the Google toolbar. It must be happening to a lot of people, because I couldn’t find anything on it, so I posted this article. In five hours since I posted it, there is a virtual stream of queries from Google coming in with "tbn0.google.com" and "certificate". I don’t really need the toolbar. Other addons have replaced its functionality and done a better job of it. So I took it off. No messages so far.

I don’t think it’s related to the toolbar, as I’ve been getting something similar for the past few days. Whenever I do a Google Image Search (GIS), I get a similar, if not the same, error.

Security Error: Domain Name Mismatch

You have attempted to establish a connectino with “tbn0.google.com”. However, the security certificate presented belongs to “www.google.com”. It is possible, though unlikely, that someone may be trying to intercept your communication with this webs site.

If you suspect the certificate shown does not belong to “tbn0.google.com”, please cancel the connection and notify the site administrator.

Veiw Certificate, OK, Cancel

I hit cancel, and when I do, one or more thumbnails do not display. However, if I go forward a page and come back… or back a page and go forward, I usually do not get the error, and all thumbnails display correctly.

So… I have no idea, other than this is the first site that came up when I googled tbn0.google.com

Did anyone ever get to the bottom of this?

Nope. Who knows what is? Google is like the government now. They don’t have to have answers for what happens with their system. But then again I stopped looking once it stopped happening.
