I installed the jdk 1.6u7, and then I open firefox, I see there is a java console 6.0.07 in extension, but in plugins, there is no java. and I can't open java website, it shows I don't install java in my machine, but actually, I have installed jdk 1.6u7. I think only if the java exists in plugins, the website can get the jvm and run.

it seems it is ok if I install a jdk which will create a plugin in plugins, and the extension can't be used.

You need the Next-Generation Java™ Plug-In present in Java 6 U10 and later (Linux:; Windows: npjp2.dll).

You would need JRE (Java Runtime Environment) to run Java programs. You can try to click the download button on the page (above image) or you can download the latest version here:

Thanks for your reply!

I download the jdk file: jdk-6u7-windows-i586-p.exe, after I click it and install, it installed both the jdk and jre, I can see 2 folders: C:\Program Files (x86)\Java\jdk1.6.0_07 and C:\Program Files (x86)\Java\jre1.6.0_07.

Is the JRE in jdk file are different from the pure JRE file? let me try....

And I need to run the oracle forms 12.1.3, it requires JRE 1.6.0_07...

I think the runtime included with JDK (Java Development Kit) may not extend to web functionality. It may be strictly for development/testing purposes. Please also note that many versions of Java prior to the latest 1.6.33 in the 1.6.x series are automatically blocked by Firefox due to severe vulnerabilities.

install the pure JRE file, the same, can't see plugin in plugins.

then I install jdk-6u16-windows-i586.exe, it works:

Verifying Java Version A newer version of Java is available

Please click the download button to get the recommended Java for your computer. Your Java version: Version 6 Update 16

so... I can only understand as that the firefox 13.0.1 does not support java 1.6.0_07...

Possibly it could be like that :)

Like cor-el said, you need the "Next Generation" Java plugin found in Java 6 Update 10 and above. The Java Console you see in the Extensions list is an outdated add-on for Java 6 Update 7, which is a version of Java that is too old to work in Firefox.

Additionally, older versions of Java may be blocked by Firefox for security reasons so you should make sure Java is up-to-date.

The Java Update feature lets you check for updates from the Java (32-bit) Update tab in Windows Control Panel. To update java manually, go to and download the latest version of Java, currently Java 7 Update 5, then close Firefox and run the installer. You will then see Java(TM) Platform SE 7 U5 in the Firefox Add-ons Manager Plugins list when you next open Firefox. You can check your Java version using the test links here.

If for some reason you need the Java Development Kit (JDK), rather than the JRE that you need for Firefox and other browsers, you can get it here:

Thanks all for help.
