Java not working in Firefox

I am having trouble getting Java to work in Firefox (Opera too) on Mac. http://www.java.com/en/download/installed.jsp?detect=jre tells me "We are unable to verify if Java is currently installed and enabled in your browser." Notice that when I access the page, Firefox wants me to activate Java in a pop-up. I did this.

I know that Java is installed because I can open the Java Control Panel. The setting "Enable Java content in the browser" is checked and Security Level is set to High. I have tried setting the security level to a lower setting, but that doesn't help.

I have verified that the Java plugin is enabled. I have tried clearing Java cache via the control panel - no luck.

I realise that Apple has blocked Java according to this article: http://appleinsider.com/articles/13/01/31/apple-again-blocks-latest-version-of-java-through-os-x-anti-malware-system. I have been able to get Java to work with Safari (this doesn't help for Firefox) by editing the file /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist, but that is only a temporary solution, as it shouldn't be necessary to do this edit.

Version details: Mac OS X 10.8.2 Firefox 18.0.1 Java version 7 update 11

Hello epb9, your solution is the only one that maybe works right now, see AliceWyman's reply in the next link: https://support.mozilla.org/en-US/forums/contributors/708898?last=50518#post-50518

thank you

Yeah, it says that it is the only way to get it to work in FF. But that solution only works for Safari on my computer :(

I have now installed java 7 update 13. Now it works in Safari without any tweaks, but it still doesn't work in FF (or in Opera).
