Multiple Java Console add-on in Firefox

I recently discovered more than one Java console add-on inside my add-ons manager in my Windows 7 machine. Since I only had only one version of JRE (Java Runtime Environment) updated to the latest version, this did not make sense. To make it more of an eye-sore, these add-ons did not have an associated "Remove" button in the add-on manager.

Some Google-ing revealed these are Java update left-overs. They do not have the "Remove" button because they are installed inside the %ProgramFiles(x86)%\Mozilla Firefox and not inside the %AppData%\Mozilla\Firefox profile directory.

In my installation, I had the following directories inside %ProgramFiles(x86)%\Mozilla Firefox\extensions directory:
  • {CAFEEFAC-0016-0000-0026-ABCDEFFEDCBA}
  • {CAFEEFAC-0016-0000-0023-ABCDEFFEDCBA}
  • {CAFEEFAC-0016-0000-0017-ABCDEFFEDCBA}
The blue numbers are indicative to the Java versions. To remove older left-overs, just keep the folder with associated with the latest Java version, which usually is the highest number in the list and delete the others.
