Mozilla Delivers SeaMonkey 2.0
Mozilla is out with version 2.0 of its SeaMonkey hybrid browser and email platform, based on Firefox and Thunderbird. There is a long list of additions to the new version, which you can peruse here. SeaMonkey didn't use the exact same core as the Firefox browser before, but now shares the the core of Firefox 3.5.4. Among other things, that means extensions should work more dependably than they did before. Here are some of the other important improvements.
SeaMonkey 2.0 builds in a new add-on manager to make working with extensions as similar as possible to using them in Firefox.
Tabbed mail is now supported, and you can dedicate to tabs to separate email accounts, or use them to organize folders.
Toolbars are now fully customizable.
The MailNews component now includes support for reading RSS and Atom feeds.
Session restore (crash recovery) has been added.
SeaMonkey 2.0 is downloadable for Windows, the Mac or Linux here. Many people who like both Firefox and Thunderbird favor it as an integrated platform for browsing and email, and version 2.0 is definitely a major upgrade.
