Thunderbird makes e-mailing safer, faster, and easier with such features as intelligent spam filters, a built-in RSS reader, and quick search. Thunderbird was designed to prevent viruses and to stop junk mail. Thunderbird 3 includes tabbed e-mail, new search tools and indexing, "smart" folders, support for Firefox's Personas, a simplified setup wizard, and robust junk protections that include phishing and spam filters.
Thunderbird 3 is based on the Gecko 220.127.116.11 platform including some major re-architecting to provide improved performance, stability, web compatibility, and code simplification and sustainability.
