Java not working in Firefox

I am having trouble getting Java to work in Firefox (Opera too) on Mac. 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: 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:

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).
