Hello there, First, you just published your address onto a public forum readable by the entire internet. I removed it, but please be more careful going forward.

Second, this is the Mozilla Firefox support forum. We can help you with issues in Firefox, your web browser, but we keep no records of anyone's address, so we can't fix that. I imagine you are wanting to change your address on some shopping website, perhaps amazon? I suggest you contact their support for help.
