I have a Mozilla/Firefox Account, but when attempting to set up a monthly donation, the message says, ". . .Is this the right email address? We couldn’t verify that this email address is able to receive mail." It is the same email address used on the Firefox Browser and accessable with a password, so I'm puzzled as to why it is questioning the ability to validate the email address. Please help. I would very much like to donate. Kind regards. Joe
