Thanks, Everyone
Lord Boltar, I did what you said, box was already checked for autofill, but it gave me the option to add addresses, I added mine. It seems to work on a test, it worked, but I get a prompt to click on my autofill entered address to put it in. I'll assume that is how firefox works which is not the same as Chrome. It's more of a semi-auto autofill, I like FULL-auto, oh well!
Thanks again!
