When Java is disabled in the Content tab, under Preferences, the browser information still shows that Java is enabled. Checking "about:plugins" in the URL shows all plugin information and shows that Java is still enabled.
However, if you try and run a Java applet, it does not work because Java is disabled.
Steps to Reproduce:
1.Open Firefox and go to Preferences.
2.Click on Content tab and deselect the "Enable Java" check box.
3.Type "about:plugins" in the Firefox URL.
4.Java plugins still show as enabled.
Java plugins still show as enabled. Java plugins show "Yes" under the enabled column.
The Java plugins shoud show say "No" under the enabled column.
The software should report that the Java plugins have been disabled.
The information displayed in about:plugins for the Java Embedding
Plugin is static -- it's compiled into a binary, and can't be changed
according to how the browser's settings change. The same thing is
true for the Sun Java Plugin on Linux and Windows.
Since there's no way to "fix" this problem, I'm marking it WONTFIX.
But it's still possible to use the Java Embedding Plugin's
about:plugins display to determine whether or not Java is enabled:
Click on the "Java Information" link (after "Run version test) -- if
you've disabled Java, it will tell you that "Java is NOT enabled".
