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. --------------------------------------------------------------- This message and any attachments may contain Cypress (or its subsidiaries) confidential information.
