GENERAL  INFORMATION

Mozilla® Thunderbird^TM is the e-mail client and news group reader successor to the Mozilla browser suite 1.7.x released as part of the OpenServer 6.0.0 product. Like the former releases of Mozilla for SCO platforms, Thunderbird is built from the source code open-sourced by the Mozilla Foundation. What previously was a single application with multiple functionality is now released as separate products; the e-mail client and news reader functions are provided by Mozilla Thunderbird. Firefox® which provides the browser and file download features is available as a separate installable component on the OpenServer 6.0.0 Support/Supplements Download web page. The ChatZilla internet relay chat (IRC) feature of Mozilla is available through a Firefox add-on extension.

While Thunderbird is the ultimate replacement for the Mozilla e-mail client on OpenServer 6.0.0, installation of this Thunderbird release will install in parallel with the existing Mozilla suite. Installation of Thunderbird will not automatically remove Mozilla from your system. Because the functionality provided by the earlier Mozilla suite is now provided by separate applications, there is no simple way to automatically replace the Mozilla suite with the new Thunderbird e-mail client. Allowing both e-mail clients to be active on the system provides each site the opportunity to switch from Mozilla to Thunderbird at their convenience. If users have been using the Mozilla browser, the Mozilla Firefox application will also need to be installed.

See the configuration discussion in the "Firefox Installation" section of the Firefox README.html as well as the "Removing the Mozilla Browser Suite" section below.

Configuration

Profiles

Thunderbird, like the Mozilla e-mail client, maintains a user's default profile containing that user's preferences, e-mail accounts, message filters and saved passwords. For Mozilla, that profile was typically in $HOME/.mozilla, with:

default/<random-string>.slt/ Default User/<random-string>.slt/		typical initial/default profile directory
<profile-name>/<random-string>.slt		named/additional user profile directory

These are the same profile directories of the Mozilla browser suite with subdirectories for each e-mail account.

Thunderbird maintains user profiles in $HOME/.thunderbird, with:

<random-string>.default/		typical initial/default profile directory
<random-string>.<profile-name>		named/additional user profile directory

When a user starts Thunderbird for the first time, a default user profile is created and the application will step the user through the process of setting up the e-mail account or news group account. If a previous Mozilla profile exists, the user may import that profile including all e-mail and news group accounts and address book information.

Migrating Mozilla E-Mail Local Folders

The import of Mozilla e-mail information does not move or copy (duplicate) any e-mail that has been saved in the the "Mail/Local Folders" directory tree of the Mozilla .profile directory. Users who want to bring theses folders along will need to "import" them manually. The most most straight forward approach is to copy the "Local Folders" directory into the new Thunderbird profile. Using the information above, determine the names of both the Mozilla and Thunderbird default profile directories.

cd $HOME/.mozilla/<mozilla-default>/Mail
find "Local Folders" | cpio -pcdum \
   $HOME/.thunderbird/<thunderbird-default>/Mail

Importing Mail Folders From Other Sources

There are extensions or add-ons for Thunderbird that will provide a means to import mbox or eml formatted mail files from other e-mail tools. For complete directions and a link to such extensions, click on the "Thunderbird Help" link in the Documentation section below. A search for "import local folders" will retrieve a mozillaZine article on "Importing and exporting your mail" with complete directions.

Preconfigured URL Link Handlers

With the Mozilla e-mail client, clicking on a link to an http or ftp URL would bring up Mozilla browser window and the URL accessed. Now that the e-mail and browser functionalities are in separate applications, the e-mail client must have some method to determine what application should be used to handle various Multipurpose Internet Mail Extensions (MIME) types.

On UNIX/Linux systems, Firefox and Thunderbird attempt to use the GNOME desktop configuration runtime. To do so on OpenServer 6.0.0, would require a third desktop runtime to be installed and this seems like over-kill. For OpenServer 6.0.0, the Thunderbird application has been preconfigured to use the user's or system wide selected graphical browser accessed by the script /usr/bin/browser. The following default preferences have been added to the file /usr/lib/thunderbird/defaults/pref/all-sco.js

pref("network.protocol-handler.app.http", "/usr/bin/browser"); pref("network.protocol-handler.app.https", "/usr/bin/browser"); pref("network.protocol-handler.app.ftp", "/usr/bin/browser"); pref("network.protocol-handler.app.gopher", "/usr/bin/browser"); pref("network.protocol-handler.app.chrome", "/usr/bin/browser");

Individual users can modify these settings, if desired, in their Thunderbird preferences. Select "Preferences" from the "Edit" menu; then click on "Advanced" in the "Thunderbird Preferences" wizard. In the "Advanced" section, under the "General" tab, select "Advanced Configuration" by clicking on the "Config Editor button". Bring up a change window by either double clicking on the preference name to be modified or right click on the preference name and select "Modify". Enter the path name of the tool to be used for that MIME type.

User Customization

Users are encouraged to tailor the Thunderbird e-mail client to make it "perfect" for themselves. Customization possibilities include:

• toolbar customization: rearranging toolbar items; adding, hiding and deleting toolbars
• add-on themes: changing the appearance, look and feel of Thunderbird
• add-on extensions; new functionality for Thunderbird from a new button to a complete new feature.

The "Customization" section of the Mozilla Firefox Help wizard will provide guidance on making toolbar changes, getting and installing add-ons, and using the Add-ons Manager.

Add-ons hosted on the Mozilla.org web site can be accessed from the "Thunderbird Add-ons" link in the documentation section below or by using the the Add-ons Manager within the Thunderbird application. To bring up the Add-ons Manager, click on the "Add-ons" entry in the "Tools" menu. The Add-ons Manager will show what extensions and themes are installed and enabled. To search for and download extensions or themes, click on the "Get extensions" or "Get themes" link. When installed, the add-on appears as a new entry in the "Tools" menu.

Caution !!! If an add-on is for a specific operating system or provides buttons to select an add-on download based on operating system, do not attempt to download and install. Clearly the feature is operating system specific; and if it contains a plugin library, it may cause your browser to crash or worse.

DOCUMENTATION

REMOVING the MOZILLA  BROWSER  SUITE

Once Firefox has been installed and Thunderbird installed for current Mozilla e-mail client users, the system administrator can prepare to remove the "old" Mozilla component from the system. Review the information in the "OpenServer 6.0.0 Default Graphical Browser Setting" sub-section in the Firefox README.html. The systems administrator (root), should:

1. Reset the graphical browser in /etc/default/browser if previously configured to execute the mozilla executable.
2. Scan the HOME directories of all users and if it contains a .browser, remove any such file that points to the mozilla executable.
3. Any third party or in-house application that directly uses the mozilla browser should be modified to use the Firefox executable directly (/usr/bin/firefox) or the generic browser script (/usr/bin/browser).

• /bin/mozilla
• /usr/bin/mozilla
• /opt/mozilla/mozilla
• /usr/lib/mozilla/mozilla

When the three steps above have been completed, it is safe to remove Mozilla from your system. Once removed, Mozilla will not appear in the /usr/bin/browser list of available browsers.

A very early release of Mozilla 1.7.x is on the OpenServer 6.0.0 installation CD1 and that will be installed by default on all fresh installations. That Mozilla component should be removed and Firefox and optionally Thunderbird installed before allowing users to configure a "default" browser or setting the system -wide browser default.

When you are ready to remove the Mozilla Browser Suite from your system, as root, run the Software Manager with either of the commands - "scoadmin software" or "custom", or double-click on the Software Manager icon on the desktop. Highlight the "Mozilla Web Browser (ver 1.7.xx)" and select the "Remove Software..." item on the "Software" menu.
