Java FAQ - Java working on Konqueror, but not Firefox

'Note: The Java plugin has only been tested with the Firefox and
Mozilla browsers. If it works well for you using a different browser,
please let us know.'

For me, using OpenBSD 4.2, i386, OpenBSD port for Java 1.5.0_12, Java
works on Konqueror 3.5.7, but not Firefox 2.0.0.6.  In Firefox,
attempting to load a Java applet results in the browser crashing.

To configure Konqueror to use Java, go to Settings -> Configure
Konqueror -> Java & JavaScript -> Java
Under 'Path to Java executable, or java', enter:
/usr/local/jdk-1.5.0/bin/java

For some reason, Konqueror loads the Java applets outside of the
browser window, but otherwise they work fine.
