Java works in Internet Explorer but doesn't work in FireFox.

My installed Java-related programs are: Java 7 Update 11 Java 7 Update 11 (64-bit) Java SE Development Kit 7 Update 11 Java SE Development Kit 7 Update 11 (64-bit)

I don't have JavaFX or anything else. I need both kits for Eclipse and other things.

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

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

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
