hello, is this a question about thunderbird? (at the moment it's posted in the firefox product section of the forum)

HI, thanks for answering. I use Mozilla Firefox.

Firefox doesn't do email, it's strictly a web browser.

If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.

Thanks Edmeister. I have already contacted them; but thought there may be an easier way to back them up.
