SeaMonkey saves your personal information such as bookmarks, passwords, mail and news messages, installed add-ons and user preferences in a set of files called your profile, which is stored in a separate location from the SeaMonkey program files.

What is a profile?

Any changes you make while using SeaMonkey are stored in files so that they can be used the next time you run SeaMonkey. These changes can be obvious, like your home page, mail and news messages, or changes you've made to the toolbar, but also include things like your history, what sites you've visited, which messages you have read, and text you've entered into forms like search fields. They're all stored in the same location, called a profile folder.

These files are kept separately from the program files that SeaMonkey uses to run, which don't change. This means that you can uninstall SeaMonkey without losing your settings, and that if something goes wrong with an update your information will still be there. It also means you don't have to reinstall SeaMonkey in order to clear your information, or troubleshoot a problem.

How to find your profile

Each profile is stored on your hard drive in a profile folder, which is located in one of the following locations depending on your operating system:

Windows Vista, Windows 7 Users\<UserName>\AppData\Roaming\Mozilla\SeaMonkey
Windows 2000, XP, Server 2003 Documents and Settings\<UserName>\Application Data\Mozilla\SeaMonkey
Mac OS X ~/Library/Application Support/SeaMonkey
Linux and Unix systems ~/.mozilla/seamonkey

Those are the typical locations used by SeaMonkey 2.0 and later. When managing profiles, you can manually select different locations.
SeaMonkey 1.x does not share this location of the profile folder and uses data from an independent location.

Making changes to your profile

See SeaMonkey's integrated help system (available by opening the Help menu and selecting Help Contents or by pressing the F1 key) for detailed explanations of how to create, manage and delete profiles.

Migrating profiles

See the Knowledge Base article on Profile Migration for the steps you need to take in order to migrate a profile from Netscape, Mozilla, Thunderbird or SeaMonkey 1.
