I've tried rebooting mulitple times. I've uninstalled/reinstalled only to get the same message. I tried the "cor-el" suggested solution of deleting the (C:\Program Files\Mozilla Firefox\) first but was unable to delete the file "{CAFEEFAC-0016-0000-0025-ABCDEFFEDCBA}" as access is denied. I even tried deleting the "parent.lock" file only there isn't one in my profile folder. I believe I've now exhausted all current suggestions. Please help!

Were you ever able to delete {CAFEEFAC-0016-0000-0025-ABCDEFFEDCBA}? If not, try downloading Unlocker and seeing what application has a hold of it. (http://www.emptyloop.com/unlocker/)

FYI - I also emailed one of the peers on the installer for insight on what we can check as I have seen several reports on the forums lately with similar issues.

That is one of the Java Console extensions.
