When you open the Plugins page in Firefox addons (typing about:addons in the address bar), you may notice one Java Deployment Toolkit plugin there. You can set it to Never Active from the menu options, but there is no way to uninstall java deployment toolkit from within Firefox.
What Does Java Tool Kit Plugin Do?
According to the java official website,
The Java Deployment Toolkit is used by Java applets and applications to help manage to get the right version of Java for a user’s system. For developers, it also provides a JavaScript interface. The interface automatically generates the HTML code that is required to deploy Rich Internet Applications (RIAs).
What that means is that the Java Deployment Toolkit provides the information about what versions of the Java Platform end users have installed on their PCs. This greatly increases the ease of detections of users’ Java environment, as well as the ease of Java Platform deployment.
Even with java in use, you can uninstall java deployment toolkit. The confusion arises because of the confusion between Java and JavaScript.
Java Vs JavaScript
The main confusion among users regarding the plugins comes from the fact that Java and JavaScript are two different aspects altogether. Java is an OOP (Object Oriented Programming) Language that can be run in virtual machines as well as browsers, while JavaScript is an OOP Scripting language that can be run in browsers only.
Java is not an integrated service in web browsers and is not used by a lot of websites anymore. The Java Deployment Toolkit only provides a version number to the websites that use java, so it is not necessary to keep it in your system.
How To Uninstall Java Deployment Toolkit?
The Java Uninstaller does not remove the plugins and addons it installs. You have to remove java manually. Here I will show you how to uninstall java deployment toolkit.

- Type the following command to open the address:
C:\Windows\system32 - Here search for dll and npDeploytk.dll in the file explorer.

C:\Program Files (x86)\Java\jre6\bin\new_plugin\
Removing these files from their plugin locations also removes them from being used as plugins in Firefox.
