See the the two bugs and confirm if either one of these two are related. There is not enough information you recently gave us to help us to get better pictures of this bug. Bug #1 http://bugzilla.mozilla.org/show_bug.cgi?id=163242 Bug #2 http://bugzilla.mozilla.org/show_bug.cgi?id=163184 Did you delete the Mozilla.org directory first before installing the latest nightly build? If not, do so and tell us about what you got so far.

We have been having trouble with these bugs because there is not enough information.

See bug #160255 as reference.

Sorry for spamming. I'm trying to find all of hte reference and see what we can come up with. The only thing in common I see are Windows (ALL). See bug #162567 as reference. See bug #163083 as reference. See bug #162192 as reference. Very important, bug #126826, the original bug of all. Guilty Party???

Sorry for the dup. Didn't see the other bugs. Yes, deleting the moz dir and reinstalling fixes this problem. *** This bug has been marked as a duplicate of 126826 ***
