Released on 11 Jan 06, and this changelog was last updated on 23 Apr 06.

Mozilla Thunderbird 1.5 has been released. Release notes are available. This post lists the improvements in Thunderbird 1.5 over the previous aviary branch release 1.0.7. Do note that this list is not exhaustive. It is based on previous changelogs for versions 1.1a1, 1.1a2, 1.5b1, 1.5b2, 1.5rc1 and 1.5rc2.

Generally, with the release of 1.5, the stability of the program has been improved immensely, coupled with better search capabilities compared to the 1.0.x Aviary branch releases. Attachments can now be deleted from emails while support for podcasting, Google Maps and improved spam filtering have been added. Additionally, there is a built-in phishing detector and the program now auto-saves drafts, so in case the program or OS crashes, the draft will not be lost. Spell checking while typing is now possible, and software update improvements have been implemented similar to that of Firefox 1.5.

New features:

  • 2920, 288273, 298860: Deleting attachments from messages.

Impact key for security issues listed on the Mozilla Foundation Security Advisories webpage:

  • Critical: Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.
  • High: Vulnerability can be used to gather sensitive data from sites in other windows or inject data or code into those sites, requiring no more than normal browsing actions.
  • Moderate: Vulnerabilities that would otherwise be High or Critical except they only work in uncommon non-default configurations or require the user to perform complicated and/or unlikely steps.
  • Low: Minor security vulnerabilities such as Denial of Service attacks, minor data leaks, or spoofs. (Undetectable spoofs of SSL indicia would have “High” impact because those are generally used to steal sensitive data intended for other sites.)

Improvements over Thunderbird 1.5 RC 2:


  • None. If you have already installed RC 2, then you have the 1.5 final release.
If 1.5 is installed over a previous version (prior to 1.5 final, including RC 2), some users are reporting the program may not start. In this case, the program should be uninstalled, backing up the profile in the process, and reinstalling the application.
