Java SE Runtime Environment 1.7.0_01 Incompatible with Firefox 7.0.1

Avast Free Antivirus / Premium Security

Having upgraded to Java Standard Edition Runtime Environment 1.7.0_01, it is reported by Firefox Add-on that Java Console 7.0.01 is not compatible with Firefox 7.0.1. I am puzzled if which party should take appropriate action on remedying the adverse condition.

My apologies as I have posted my query wrongly. However, the Firefox Add-on Compatibility Report has indicated that avast! WebRep is not compatible with Firefox 7.0.1 - a compatibility problem. A little technical help is highly appreciated.

Strange the fact of WebRep… Are you really using the last Firefox and avast versions?

First of all: Java 1.7xxx is compatible with FF 6+ !
There is only one term in the “install.rdf” from Java Plugin which obviously does not work on all systems.

Solution:

  1. Get into your user account and draw the slider all the way down and reboot the system.
  2. Navigate to your install folder of Mozilla Firefox\extensions{CAFEEFAC-…} with the youngest date/time stamp.
    (You can delete all the older ones starting with the same characters. They are leftovers from older installations which are also still showing up in Firefox plugins!)
  3. In the youngest folder open “install.rdf” with editor.
  4. Search for the line: em:maxVersion…</em:maxVersion>
  5. Alter the line so as to look like this: em:maxVersion*</em:maxVersion>
  6. Save the file.

Everything should be working now!
You may want to reset your user account to the original setting now and reboot the system.

If you install an update of Java you may have to do the same procedure again.

Java Console is not necessary to the function of Java. If you are troubleshooting Java applets, the you might have a need for it. I routinely delete all the folders that JRace mentioned in Item #2 without adverse effect. Do so with Firefox closed to be safe.

You must be running an older version of Avast. Avast 6.0.1289 WebRep is fully compatible with Firefox 7.0.1.

Confirming this.
And btw, it’s also compatible with all newer/upcoming versions of FF…!! :wink:
