It's broken regardless. Try this: install Oracle's java and link the plugin
into /usr/lib64/mozilla/plugins. Run firefox and go to about:plugins. No
java in sight. Then close firefox and, as root, link the java plugin into
/usr/lib64/mozilla/plugins-wrapped. Run firefox again and go to about:plugins.
No java. Close firefox and look at /usr/lib64/mozilla/plugins-wrapped; the
java plugin link is now gone.
There are several unexpected features here. First, the firefox wrapper uses
.../plugins-wrapped instead of .../plugins if mozilla-plugin-config is
found, i.e. nspluginwrapper is installed. So no matter what you think you're
installing into .../plugins has no effect whatsoever. Secondly,
mozilla-plugin-config removes the java plugin from plugins-wrapped and it is
unclear why - in typical Linux fashion, there is no documentation on what
exactly it does, how it does it, and there seems no way to configure it.
Third, why is mozilla-plugin-config messing around in system dirs in the
first place when a user runs firefox? Here's the answer:
$ ll /usr/lib64/nspluginwrapper/plugin-config
-rwsr-xr-x 1 root root 60432 Jul 17 2008 /usr/lib64/nspluginwrapper/plugin-config
$
SUID? WTF? This is on CentOS 5.4 btw, but the firefox wrapper hasn't changed
in 5.5.
Essentially, this behaviour renders all the well-meaning firefox+java setup
guides useless. And unless I'm mistaken, nspluginwrapper is needed for 32-bit
binary blobs like flash and adobe.
Next, I haven't yet successfully managed to get java to work on x86_64 with
the 32-bit browser. Installing the 32-bit plugin from the corresponding jre
doesn't seem to be enough.
