File: JavaAppletPlugin.plugin
   Version: 14.0.3
   Displays Java applet content, or a placeholder if Java is not installed.

When I visit https://www.mozilla.org/en-US/plugincheck/ the page reports that the status of my Java Applet Plug-In is "Vulnerable." After the first time I received the warning, I went to https://support.apple.com/kb/DL1421 and downloaded what I believe is the most recent Java update, 1.6.0_29. I installed that update (apparently successfully, according to the installer), restarted Firefox, cleared my browser cache, and checked again. It did not appear to help. Additionally, the following is my Java Applet information, copy-pasted from the "About Plugins" page under Help>Troubleshooting Information. I notice that this question page has detected only explanatory text regarding the Java Applet plugin, and not its version number. Therefore: Java Applet Plug-in File: JavaAppletPlugin.plugin Version: 14.0.3 Displays Java applet content, or a placeholder if Java is not installed.
