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.
