Firefox 26 for OS X apparently blocks Java now permanently - without possibility to activate it. See these pictures: https://fotos.gmx.net/ui/external/NU4MGj9rQkacbe7pt4Bm4A08601 On the left is Safari 6.1.1 (with Java working after getting permission), on the right is Firefox 26 (claiming that there is no Java installed). Both show the same website and exactly the same is happening on all websites that require Java. Another example are websites with VoIP tests (i. e. http://voiptest.8x8.com/). As you can see in the pictures the latest version of Java for OS X (Java 7 Update 45) is installed and enabled. Is this the same or different for other Firefox 26 users, or is there a way to get Java working in Firefox 26 for OS X?
