SeaMonkey 2.1 Beta 3

Mozilla has issued a third beta for version 2.1 of its SeaMonkey "all-in-one internet application suite". SeaMonkey is the successor to the old Netscape Communicator and Mozilla Application suites and includes a web browser with advanced email and newsgroup support, an IRC chat client and HTML editing support.Based on the same Gecko layout engine as the 3.6.x branch of Firefox, SeaMonkey 2.1 Beta 3 features support for 3D graphics via WebGL and an easy setup process for SeaMonkey Sync (Firefox Sync).
other changes in SeaMonkey 2.1 on Mac OS X is the addition of support for tab switching using mouse scrolling, Windows 7 Jump Lists and displaying download progress in the Windows 7 taskbar. ChatZilla and the Venkman JavaScript Debugger are also said to be working again. The 2.1 branch no longer supports Mac OS X 10.4 Tiger systems as it requires some newer features only available in 10.5 or later.
SeaMonkey 2.1 Beta 3 is available to download for Windows, Mac OS X and Linux in 13 different languages from the project's site.
