The Mozilla Thunderbird project is a redesign of Mozilla's email/news component, written using the XUL user interface language and designed to be cross-platform.
Clarification: "Mozilla Thunderbird" is just a project name, in the same way as the Mozilla Application Suite is codenamed "SeaMonkey". For more details, read about the Mozilla Branding Strategy and the Mozilla Roadmap.
If you're interested in where we're going and when we expect to get there then you probably want the Mozilla Thunderbird Roadmap.We track bugs using Bugzilla.
Because the project is small and tightly managed, bugs targeted to a particular milestone generally will be fixed by that milestone. In fact, our milestone releases are bug-driven, not date-driven. Before filing any bugs on Mozilla Thunderbird, please read the bug filing instructions.
