Hi Jim, your question posted to the support forum. There are actual humans reading and replying to questions here, but it is a holiday weekend in the U.S., so you probably won't see any Mozilla employees online right now.

What settings are you looking to change?

P.S. The forum doesn't receive emails, so please return to your thread here to follow up.

I posted an answer to your other question: https://support.mozilla.org/questions/1493511
