How to enable JavaScript after downloaded ff25 running on Mac OS 10.8

more options

Since I updated to FF25 I can't enable JavaScript which I need for sites I use. I have the latest Java 7 version 45 but there is no plug-in appearing for Java. I added Quickjava 2.0.2 I think this is the version, and clicked to enable java. But when I visit the sites that require JavaScript I get an error message saying JavaScript not enabled. When I test the java 'latest version' test from Java's web site using FF java cannot be detected, but it can when I do the same test using Safari.

How do I fix this? Tx Jo

You can check the Security tab in the Java Control panel to make sure that you have enabled Java for browser (Firefox).

Are you wanting to enable Java or Javascript, they are both totally different technologies

Thanks Cor-el this helped me solve my problem - neither Java nor JavaScript were recognised by Firefox :-)
