Installation and Uninstallation

Installation

Please note that installing SeaMonkey will overwrite your existing installation of SeaMonkey. You won't lose any of your bookmarks, browsing history or mail and news messages, but some of your extensions and other add-ons might not work until updates for them are made available.

Windows Installation Instructions

For Windows 2000/XP systems, you need Administrator privileges to install SeaMonkey. If you see an "Error 5" message during installation, make sure you're running the installation with Administrator privileges.

Windows may warn you that it could not verify the publisher when you try to run the installer. This is because the SeaMonkey installer for Windows is not digitally signed. As long as you downloaded the installer from either www.seamonkey-project.org or mozilla.org, you can safely ignore it (more experienced users may use the checksums linked to from the download pages to verify the integrity of the installer).
Windows Vista/7 will by default present you with an additional warning after extracting finished. You also need to confirm this User Account Control warning in order to proceed with the installation.

To install SeaMonkey by downloading the SeaMonkey installer, follow these steps:

  1. Click the Download link in the Windows column on the site you're downloading SeaMonkey from to download the installer file (SeaMonkey Setup 2.1.exe or similar file name) to your machine.
  2. Navigate to where you downloaded the file and double-click the installer file icon on your machine to begin the Setup program.
  3. Follow the on-screen instructions in the setup program (see the note about Unknown Publisher warnings above). The program starts automatically the first time.

To install SeaMonkey by downloading the .zip file and installing manually, follow these steps (normal users should NOT do that but use the installer as described above):

  1. Go to a Mozilla FTP server or one of its mirrors, navigate to the appropriate SeaMonkey releases directory and the subdirectory for your language in its win32 subdirectory. Click the link to seamonkey-2.1.zip (or similar file name) in there to download the .zip file to your machine.
  2. Navigate to where you downloaded the file and double-click the compressed file.

    This step assumes you already have a recent version of WinZip (or a similar zip tool) installed, and that you know how to use it.

  3. Extract the .zip file to a directory such as C:\Program Files\mozilla.org\SeaMonkey.
  4. To start SeaMonkey, navigate to the directory you extracted SeaMonkey to and double-click the seamonkey.exe icon.

Mac OS X Installation Instructions

To install SeaMonkey, follow these steps:

  1. Click the Download link in the Mac OS X column on the site you're downloading SeaMonkey from to download the disk image file (SeaMonkey 2.1.dmg or similar file name) to your machine.
  2. Double-click on the .dmg file. The disk image will now mount and a new Finder window should appear.
  3. Drag the SeaMonkey icon to the Applications folder.
  4. Eject the disk image.
  5. If you want SeaMonkey to be accessible from the Dock, simply drag the SeaMonkey icon from the Applications folder to the Dock.

Linux Installation Instructions

There is no installer available, but just extracting the tar.bz2 to the default directory (usually /usr/local/seamonkey) achieves the same result as an installer would.

To install SeaMonkey by downloading the tar.bz2 file:

  1. Create a directory named "seamonkey2" (mkdir seamonkey2) and change to that directory (cd seamonkey2).
  2. Click the link on the site you're downloading SeaMonkey from to download the package (seamonkey-2.*.tar.bz2) file into the seamonkey2 directory.
  3. Decompress the file with the following command:

    tar jxvf seamonkey-2.*.tar.bz2

    This creates a "seamonkey" directory under your seamonkey2 directory.
  4. Change to the seamonkey directory (cd seamonkey).
  5. Run SeaMonkey with the following command:

    ./seamonkey

To hook up SeaMonkey complete with icon to the GNOME Panel, follow these steps:

  1. Click the GNOME Main Menu button, open the Panel menu, and then open the Add to Panel submenu and choose Launcher.
  2. Right-click the icon for SeaMonkey on the Panel and enter the following command:

    directory_name/seamonkey

    where directory_name is the name of the directory you extracted SeaMonkey into. For example, the default directory that SeaMonkey suggests is /usr/local/seamonkey so the full command would be /usr/local/seamonkey/seamonkey.
  3. Type in a name for the icon, and type in a comment if you wish.
  4. Click the icon button and type in the following as the icon's location:

    directory_name/chrome/icons/default/default.png

    where, again, directory_name is the directory where you installed SeaMonkey. For example, using the default directory /usr/local/seamonkey results in an icon location of /usr/local/seamonkey/chrome/icons/default/default.png.

The procedure is quite similar in the Xfce environment:

  1. Right-click the Applications Menu button, open the Panel menu, then choose Add New Items.
  2. Select Launcher and click Add, then close the Add New Items dialog.
  3. Right-click the new launcher (the one with no icon at the far right of the panel), then select Properties to open the Launcher dialog.
  4. Click the document icon with tool-tip "Add a new empty item" and fill in the Name and Command fields in the Create Launcher dialog.
    Name: SeaMonkey
    Command: directory_name/seamonkey (e.g. /usr/local/seamonkey/seamonkey)
  5. Click the "No icon" button and navigate to directory_name/chrome/icons/default/default.png. Press OK, then Create, then Close.

Uninstallation

You can remove SeaMonkey through the Control Panel in the Start Menu on Windows, by removing the SeaMonkey application on OS X, or by removing the seamonkey folder on Linux.

Removing SeaMonkey won't remove your bookmarks, web browsing history, mail and news messages, extensions or other add-ons. This data is stored in your 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

Any version of SeaMonkey 2.0 or higher that you install after removing SeaMonkey will continue to use the data from this profile folder. Note that SeaMonkey 1.x does not share this location of the profile folder and uses data from an independent location.
