Make sure Firefox is not in 32-bit mode

3. Select Get Info

Make sure the box in front of Open in 32-bit mode is not checked (if it is, clear the checkbox).

Make sure Java is enabled in the Java Control Panel

Starting in Java 7, the Java Control Panel includes the Security option, "Enable Java content in the browser", which is selected by default. De-selecting this option will prevent Java applets from running in any browser and the Java plugin will no longer appear in the Firefox Add-ons Manager. Make sure that Enable Java content in the browser is selected in the Java Control Panel Security tab. See this Java Help page for details.

Make sure the 32-bit version of Java is installed

On 64-bit Windows, if you only have the 64-bit version of Java installed, the Java plugin will not be available. Current Firefox releases are 32-bit browsers and you will need to install the 32-bit version of Java.

Make sure plugin scanning is not disabled

Uninstall JavaFX if installed

In some cases, after updating from an earlier Java version to Java 7 Update 10 or above, the Java(TM) Platform plugin is no longer detected. This can be caused by a conflict with Java and a standalone installation of JavaFX that prevents the Java plugin from being properly registered. To resolve the problem, uninstall JavaFX. For more information, see this java.com help page.

Remove outdated Java plugin files

Make sure that multiple versions of the Java(TM) Platform plugin are not being detected. For example, if Java 7 Update 51 is currently installed, the Java(TM) Platform plugin in the Add-ons Manager tab should be listed as Java(TM) Platform SE 7 U51. If you see other "Java(TM) Platform" versions listed, uninstall the older versions (see How do I uninstall Java on my Windows computer?) or else remove them manually (see Manually uninstalling a plugin).
