Chosen solution

Thanks, that was part of the solution, because it listed only the locations of the actual plugins, not the symbolic links that point to them, which was the problem.

I found all locations of the plugin by running:

% locate -0 libnpjp2.so | xargs -0 ls -lt

The plugin was, besides being in the JDK and JRE plugins directories, symbolically linked in:

  • ~/.mozilla/plugins
  • ~/.mozilla/firefox/plugins
  • ~/.firefox/plugins
  • /usr/lib/mozilla-firefox/plugins/

The last 3 of these were pointing to old JRE's. I deleted my redundant ones (keeping ~/.mozilla/plugins), and updated the plugin links in /usr/lib/mozilla-firefox/plugins/. After restarting firefox, only the latest plugin shows up!

You can find the installation path of all plugins on the about:plugins page.
