Well you are in the user support forum, so you might have tried just asking it.

Otherwise in the forum there is a "search support" box on the top right were to search for what you want.

The process you went through to get to this point where you asked your question would have offered support articles and previous support postings, if you have asked a question instead of inquiring where you need to go.

Your previous thread is at https://support.mozilla.org/en-US/questions/1439901 and was only posted 21 minutes before this thread.

To find the threads and any replies you have made, look at top right corner and hover over your name. Then either click on My Questions or View Profile.

This is a support forum and not a form of direct chat or ticket system so replies can take minutes to hours or longer.
