Firefox error message on startup

After first login, I start Firefox and I get the "Start New Session" or "Restore Previous Session" dialogue box. It looks like the system was rebooted without closing Firefox (which I do all the time), but on the first startup with the iso.

Interesting...

Ironically, we've got a new ISO which just got finished and needs to be uploaded and announced.  Look for an announcement in the next day or two.
