Hi all, I am Karusai and I plan on correcting a-lot of issues for you guys :-)
I'm not sure how exactly this error happened/happens, but I have heard stories about viruses and trojans and what not which may be possible, but not in my case. I am 22 years old, graduated a year before my planned class, and am a computing hobbyist whom enjoys most of his time with correcting security flaws and keeping a-head of the hackers. I have found that this error in my case occurred during the last series of Mozilla Firefox updates, from 3.5 to 3.5.6 to 3.6. I made several attempts at correcting the issue by uninstalling and reinstalling, with no success. Then I realized, "Clean Mozilla out of the registry, retard" XD. So I did, re-booted, reinstalled, and viola. Hope this helps.
P.s. I included a screen-shot of the error for you all.
