I sent on 01/21/2013 a topic which has disappeared :
Thread: *"The 7U11 plugin for Mozilla applications, Searching to understand failures"*
That is not a string of text that is usable to search upon.
For your question to ever get an answer, in the future you would need to provide one of two possible pieces of information:
the `messageID`, or
so that the rest of us can take a peek at that forum discussion you have described.
However, having said all that, using Google's ability to cache tons of stuff, I found your original rambling post. It was likely deleted because it had nothing to do with the topics of these OTN forums. These are technical programming forums, not end-user usage forums. You have a Mozilla functionality question.
