Please see How to allow Java on trusted sites

It isn't blocked, it just doesn't appear at all in my Add-Ons > Plugin.

Please try this: http://www.java.com/en/download/testjava.jsp

It says a plugin was needed to display this content. I tried installing Java VIA "Missing Plugins..." but it fails.

See:

Hello Infinity8, a new java update is released, Version 7 Update 13 , see : http://www.java.com/en/download/manual.jsp

try to update one more time, and see if this solve your issue (at least in windows)

thank you

I am having exactly the same problem as well.

Java isn't blocked, I have all the up-to-date versions of Java and plug-ins.

My script works fine in IE but not in Firefox (or Chrome either).

Any help greatly appreciated.

PS Java is obviously working as I visit a site that blocks use of "right mouse click" and that is fine. It's just my own Java that isn't working

To avoid confusion:

You should see an enabled Java plugin in Tools > Add-ons > Plugins and Java should show on the about:plugins page if Java is installed properly.

Apologies - you are quite right. It is my Javascript that isn't working in Firefox
