I have never had a problem when JAVA 7 was needed to use a program. Until now. Firefox will not allow me to use Java. I have to open Internet Explorer when working with any program and it works.

To protect Firefox users, Mozilla has blocked/disabled Java 7 u6 and below due to serious security flaws in the previous versions of Java 7. The security flaw would also apply to any other browser using the affected versions of Java 7. You can see the version of Java and whether it is disabled in Add-ons > Plugins; look for "Java Platform SE...". See - https://addons.mozilla.org/en-US/firefox/blocked/p138

You can check your enabled Plugins at any time - https://www.mozilla.org/en-US/plugincheck/
