Mozilla Thunderbird Help

The free Mozilla Thunderbird email management software is an excellent software. A perfectly good alternative to mainstay programs like Microsoft Outlook and Eudora, Thunderbird has the advantage of (no) price and frequent updates to keep pace with changes.

On the other hand, Thunderbird is burdened with the trouble that plagues many well-done but 'free' programs on the internet: there's no dedicated, 24/7 customer service. This page is meant to be a help to getting your download of Thunderbird up and running.

Important Link: The OFFICIAL online Mozilla help page

Download Thunderbird: MOZILLA THUNDERBIRD (free email client software for Windows and Mac OSX)

Important for you to know:

IMAP: This setting leaves email on server.

POP3: This setting downloads email to your computer, allowing offline browsing.

(If you have already set up but want to change your server type from IMAP to POP3 (or visa-versa) then create a new account which is a duplicate of all the settings: in the first account, set to POP3 (or IMAP) instead. Just give it an appropriate description name so that you can tell the two apart.)

(2) If you want to download your mail and have it delete off the mail server PERMANENTLY at the same time you can also use these alternative free email client programs:


(Windows settings first: OSX Macintosh settings - scroll further down)

Imap will leave email on the server, but allow you to organize, send, receive and delete the mail. Pop downloads the email to your computer.

email accounts if you need to manage more than one)
