[Bug 1182128] Re: Java plugin not loading in Firefox 21

[Lars Steinke]

Thanks everyone,

but as I described initially, the link to the plugin in /etc/alternatives and from there to /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64 is intact, that plugin is simply NOT loaded - not even if I add it to /usr/lib/firefox/plugins as well:
sudo ln -s /etc/alternatives/mozilla-javaplugin.so /usr/lib/firefox/plugins/libjavaplugin.so

And using the JRE6 plugin libnpjp2.so is probably rather suicidal, with
that version no longer receiving security patches...
