Hi Bill, where are you having this problem? Is it related to Firefox Sync, or to some other Mozilla site or service?

Usually an underscore is used as a substitute of a space character to separate words.
Having an underscore trailing at the end of the name is not a very common place for it, so it may be because of that if it really happens.

If it happens before you have finished entering the email address then you can ignore it.
