Firfox 17 disabled my Java, and told me to update to Java 7 Update 9 - now it does not work ("The plugin is disabled")

Posted

When I go to the Java test page (http://java.com/en/download/testjava.jsp), it says the Plugin is disabled. The Manage Add-Ons page said it was Disabled after a reboot, but is enabled now. Chrome and IE both agree that I have Java 7 Update 9 installed, and the testjava page works just fine.

A couple of sites I use frequently have embedded Java apps, so I need to get this resolved.

Try to delete the pluginreg.dat file in the Firefox Profile Folder and maybe addons.sqlite as well to reset the plugin registry databases.

You can use this button to go to the Firefox profile folder:

That seems to have fixed the problem! Now the javatest page works, as does the web site I need to get to! Thanks.
