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.

Lightning does not work with SeaMonkey when icaljs is enabled, which it is by default. As a workaround, disable icaljs by setting the calendar.icaljs pref to false in about:config.
The Remember Passwords add-on breaks password handling. Please disable or uninstall this add-on using the Add-ons Manager.
You cannot set up a new Sync account or pair a device anymore. Workaround: Use an older version of SeaMonkey for such tasks for now.
