There are several configuration choices that you can make after you have installed your browser. You can add plugins for common web technologies such as Java (java.sun.com), PDF printing (www.adobe.com), and Flash animations (www.macromedia.com/software/flash) and slightly less well-known, but very cool plug-ins, such as Enigmail (enigmail.mozdev.org).
To install any plug-in, either copy the plug-in from the source application (e.g. Acrobat5 ) to the
/plugins directory in Mozilla, or create a symbolic link from the plug-in to the plug-ins directory in the Mozilla binary tree. For example, to create a Mozilla plug-in for Adobe Acrobat 5 using a symbolic link, simply type ln -s /path/to/Acrobat5/Browsers/intellinux/nppdf.so /usr/local/mozilla/plugins/. Similarly, to create a plug-in from your Java runtime environment, type ln -s /path/to/j2re1.4.0_02/plugin/i386/ns610/libjavaplugin_oji.so /usr/local/mozilla/plugins/. Please note, it is recommended that you use Sun's JDK 1.4.1 with Mozilla 1.0.1 and above. There are known incompatibilities with Mozilla and earlier versions of Java.
To obtain Mozilla project plug-ins such as Enigmail, which provides an interface for encrypting and decrytping mail, or for Protozilla, which provides full parameterization (including support for multiple multiple protocol and programming languages), visit mozdev.org.
