被選擇的解決方法

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.
