Removing Java Console Extensions

We mentioned the Java Console Extension as one of those extensions that a program (in this case Oracle’s Java) installs into Firefox without the user’s knowledge. Unless you are a Java Developer, this extension serves no real purpose for most Firefox users. Many users find they have multiple Java Console extensions and some (or all) are disabled. However, there is no way to remove the extension(s) via the Firefox add-ons manager. A long time ago we posted on how to remove the extension and thought it may be a good idea to post it again.Especially since some users may want to perform a little housekeeping on their Firefox profile before they update to the next version.

Windows XP users should be able to remove from the add-ons manager, while Windows Vista, 7 and 8 users you will need to remove the JAVA Console extension(s) manually from within extensions folder in your Firefox install (NOT profile) folder:

  1. Locate your Firefox install folder. In most cases on Windows this is going to be C:\Program Files\Mozilla Firefox\ or C:\Program Files (x86)\Mozilla Firefox (hint: right-click on the short-cut and click properties to find the install location).
  2. Close Firefox
  3. Inside your Firefox install folder is an extensions sub folder. Inside this folder remove any folders (there may only be one) which begin with {CAFEEFAC . . . . }. Warning: Windows Vista, Windows 7 and 8 users will get a UAC alert. Make sure you are logged as admin.
  4. Restart Firefox and go into your add-ons manager to confirm the extension(s) is/are gone.

Users who move to Firefox 8 should not have to deal with this sneaky add-on with the next Java update. After the Java update is installed and the user starts Firefox, they should be presented with a screen informing them a program has attempted to install the Java Console extension. The user will be asked if they want to continue with the installation or block the installation.
