I have properly installed a symbolic link to the amd64/libnpjp2.so java plugin file in ~/.mozilla/plugins but Firefox 3.5.9, 3.6.2, and 3.6.3 refuse to see it in about:plugins (Ubuntu 9.04, 64 bit, manual install of Firefox)

I have properly installed a symbolic link to the amd64/libnpjp2.so java plugin file in ~/.mozilla/plugins but Firefox 3.5.9, 3.6.2, and 3.6.3 refuse to see it in about:plugins (Ubuntu 9.04, 64 bit, manual install of Firefox) - the same directory contains the 64 bit Flash plugin (which I had to update to make it see) and the libnullplugin.so. These are both picked up, my symbolic links to /usr/lib/totem/gstreamer/*.so files are not, but I presume they don't follow the normal architecture. I have the tar.gz version of all 3 versions of Firefox previously listed installed, I simply change a symbolic link which /usr/bin/firefox points to when I want to try a different version. My Firefox profile is from an older, 3.x version that Ubuntu 9.04 came with, however backing this up and deleting it, then letting Firefox create a new profile does not seem to fix the problem (i.e. Firefox still can't see the Java plugin). Note that it's easier to maintain a manual Java install on my machine since I have to develop with various versions of Java. I noted that java.java_plugin_library_name in about:config had an improper value for the old plugin name, I did switch it to libnpjp2.

This happened

Every time Firefox opened

== I upgraded to a manual install of Firefox 3.6.3

Are you sure that Firefox gets the plugins from the ~/.mozilla/plugins directory and not from another location. Did you try to place the symlink in /usr/lib/mozilla/plugins ?

See Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems on how to see the path of all plugins.

Yes, I am sure. 1) That is a standard location, 2) it is picking up the Flash plugin and the libnull (or whatever it's called) plugin from ~/.mozilla/plugins. Granted, neither of those are symlinks but I've never had problems with symlinks in previous versions.

As well I have tried /usr/lib/mozilla/plugins and Firefox 3.6.2, 3.6.3, and 3.5.9 do not pick up the plugins from there either.
