SeaMonkey 2.53.6 for Mac – Download

SeaMonkey is a web browser that uses the same rendering engine as Firefox, and shares some of its features, such as tabbed browsing and pop-up blocking.

The software includes an email client and Thunderbird-based chat groups compatible with .Mac and Unix Mailspool (Movemail) accounts. It also supports multiple email accounts and includes a spam filter to prevent spam. On top of that, SeaMonkey offers an IRC client: Chatzilla.

SeaMonkey also offers other features that can be very useful for web developers, such as an HTML (Composer) editor, a Javascript debugger, and a DOM inspector.
