SeaMonkey is a Web browser that shares much of the same base code as the popular Firefox Web browser. It also contains an advanced e-mail and newsgroup client, IRC chat client, and HTML editor.
The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as "Mozilla Application Suite". Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have "everything but the kitchen sink" and have it stable enough for corporate use.
Note: You MUST absolutely do a full backup of your profile before upgrading from a version earlier than SeaMonkey 2.53.1. This version of SeaMonkey makes changes to your profile that can't be reverted in cases where you need to go back to the older version.
Automatic upgrades from previous versions are currently disabled for this release. Please download the full installer from the downloads section and install SeaMonkey 2.53.7 manually over the previous version.
