Mozilla Messaging Thunderbird 3.1 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 so you can get back to reading your mail. Thunderbird provides effective tools for detecting junk mail. Its tools analyze your e-mail and identify those that are most likely to be junk. You can automatically have your junk mail deleted or you can put it in a folder you specify, just in case you like reading junk mail. View your e-mail the way you want it. Access your e-mail with Thunderbird s new three-column view. Customize your toolbar, change its look with themes, and use Mail Views to quickly sort through your messages. Thunderbird 3 is based on the Gecko 126.96.36.199 platform including some major re-architecting to provide improved performance, stability, web compatibility, and code simplification and sustainability.
