Summary: Important FireFox files → Important Firefox files such as js3250.dll suddenly go missing
Some malwares erase js3250.dll.
An example is ipv6monl.dll put in \Windows\system32.
See http://forums.mozillazine.org/viewtopic.php?t=497761 for it.
You clicked OK blindly at dangerous site? Or you executed program attached to phishing mail?
Run virus scan first.
