Firefox has disabled your outdated version of Java

This seems to happen on a regular basis now. As soon as an add-on is updated firefox has trouble detecting the correct version

In this instance i am getting "Firefox has disabled your outdated version of Java" having just installed the new version of Java (7-11). I restart firefox and it doesn't solve it, i reboot my machine and it doesn't solve it.

Re: Firefox has disabled your outdated version of Java

According to this bug on the Oracle site http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8005410 , the problem occurs because their installer did not properly recognize prior Java versions and is compounded by a problem with systems having the JavaFX stand-alone application installed.

So, if you see JavaFX in your list of installed programs (Windows: Control Panel), remove it. It might also be best to remove all Java from your system before installing the new Java.

I would recommend JavaRa to uninstall all previous Java from your system, but, sadly, it has not been updated since October 2012 and does not include and will not find more recent versions of Java files and/or registry keys.

Oracle has released Java 7 update 11 to address the vulnerability recently recognized in Java 7 update 10 and some prior versions. Java 6 update 38 was not updated; support for the Java 6 versions ends in February 2013.

Re: Firefox has disabled your outdated version of Java

Thanks for the link but the problem persists. Installed the update from the link above, rebooted my machine and firefox still reporting "For your safety, Firefox has disabled your outdated version of Java. Please upgrade to the latest version."

Re: Firefox has disabled your outdated version of Java

Hello,

That is a vulnerability problem with the New Java version, if you know how to roll back to the old one, you should for the mean time as it is being resolved by Oracle.

Thank you.

Re: Firefox has disabled your outdated version of Java

Update : Just checked again and i'm now getting "Java(TM) Platform SE 7 U5 Next Generation Java Plug-in 10.5.1 for Mozilla browsers Vulnerable (more info) Update Now"

Is this update link valid or will i just be installing another vulnerable version?

Re: Firefox has disabled your outdated version of Java

"Java(TM) Platform SE 7 U5 Next Generation Java Plug-in 10.5.1 for Mozilla browsers" is not the latest version which was released yesterday or today.

11.# is the latest.

IMHO, from what I have read this morning the latest version doesn't fix all the exploits that exist with Java. More than likely, another version will need to be issued to correct all current exploits. Plus last night I read on another Firefox support forum that a Windows / Firefox / Java 7 U 11 user encountered the same problem many of us WinXP experienced with a missing Registry line which prevented Firefox from knowing that the latest version was installed. IMO, Oracle has turned Java into a "circle jerk without a team lead"!

My advice is to leave Java disabled in Firefox (or use NoScript to disable it in a more "elegant" manner), and wait for Oracle to get their act together and fix all the exploits that exist in their product before wasting anymore of your time.

Re: Firefox has disabled your outdated version of Java

Uninstalling JavaFX has done the trick for me. I now have

"Java(TM) Platform SE 7 U11 Next Generation Java Plug-in 10.11.2 for Mozilla browsers"

"1.7.0.11 Up to Date"

thanks for your help ...

Re: Firefox has disabled your outdated version of Java
