Remove Outdated Java Plugins From Firefox Web Browser

Currently I have two Java Deployment Toolkit Firefox plugins that have red exclamation mark against them. The error message is like they are "known to be vulnerable. Use with caution.". One refers to Java 6 Deployment Toolkit and another one from Java 7.

Moreover I have Java 6 SE plugin disabled with message "Java(TM) Platform SE 6 U 26 is known to cause security or stability issues.". All these messages are there because I still have older Java versions in my computer.

If I only had latest Java 8, I wouldn't have got these error messages in Firfox add-ons page. So if you don't really need, just uninstall older Java versions and you won't get these messages anymore. But if you need to use multiple Java versions for development at different times, you need to find an alternative. Enter "about:plugins" in Firefox address bar. The page will show you details of all the add-ons installed in your browser. Just search with the plugin name like "Java Deployment Toolkit". You will get the complete file path for that plugin. Just go there and delete .dll file like "C:\Program Files (x86)\Java\jre6\bin\new_plugin\npdeployJava1.dll" in this case.

So this way you can keep multiple versions of Java in your machine and still you won't see any error message in Firefox  add-ons page as you will use plugins only from latest Java version.
