Also please note that if you have Java version 6 installed, Firefox will inform you it is not compatible with it. As with the last update, this information is incorrect and the Java works fine

When you install JRE 6 it adds an extension to Firefox that adds a menu item to the Tools menu to open the Java Console. There is an error in the set-up file for the extension that only lists it as compatible with Firefox 2 and not Firefox 2.0.0.* - This causes the extension to be disabled when you upgrade Firefox, but JRE 6 will still work normally. The only difference is that you will no longer have a menu item that opens the Java Console (most people will never need this).
This extension is hidden so will not appear in the add-ons manager. The extension is installed in the application directory rather than the profile folder. If you look in the extensions folder within the application directory (default location C:\Program Files\Mozilla Firefox\extensions) the extension will be in a folder called {CAFEEFAC-0016-0000-0000-ABCDEFFEDCBA}
