Along with Java Runtime Environment, Java console extension will be installed in Firefox browser with install of Java and for each Java update new java console will be added, this way multiple Java console extensions will be installed for Firefox and these extensions are useless for end users .

If you recently installed Java 7 in your Computer, you’ll notice disabled Java console 7 under Extensions in Add-ons Manager.
