Java Console Is Incompatible With Firefox 6
Expect this issue to continue in future Firefox versions unless Oracle start updating Java more quickly… The error occurs when you update Firefox, after Firefox restarts you see the “Java Console Is Incompatible With Firefox” message.
Java Console is an add-on in Firefox installed by Oracle’s popular Java program. If you have several old versions of it installed on your computer then you will also have several versions of the Java Console add-on in Firefox – you will receive the ‘Java Console Is Incompatible With Firefox 6.0’ error message for each and every version of the Java Console add-on in Firefox.
Is There A New Version? No. Checking Firefox add-ons for updates will not find any newer version of Java Console that is compatible with Firefox 6.0
Does It Matter?
- No – unless you are a developer or have a specialized requirement you can safely ignore these incompatible Java Console add-ons errors. The Java Console is mostly a redundant add-on i.e. it is not needed for Java itself to work in Firefox.
- There is no performance loss in having these add-ons as disabled.
- You can test that Java still works properly in Firefox 6.0 by visiting Oracle’s test page here. If you have an old version it is worth updating it for general security and stability but it will not resolve the Console error message.
Warning: If you do have multiple versions of it installed on your computer, this is a security risk as malware will use (attack) your oldest version which will have security holes subsequently fixed by later versions.
You should uninstall all old versions of Java (via Add/Remove Programs or Program Features) and ensure that you have installed the latest version for best security – Oracle’s test page (see link above) will tell you if you have the latest version or not.
