As of this writing, Mozilla Thunderbird version 45.0 is available for free download and use. You can download the latest software in the language of your choice for Windows, Mac OS X, or Linux operating systems on the Mozilla web site. The page will automatically recommend the correct version for your computer's operating system. There you can also find complete, detailed instructions for its use, but be sure to read Configure the outgoing server. Near the end of these instructions, check the box labelled Use secure authentication in the Security Settings window. Also, have these Frontier-specific facts handy because you'll need them:

  • Incoming mail server (POP3):
  • Outgoing mail server (SMTP):
  • Your Frontier username (your email address)
  • Your Frontier password
