If you have Java 7 update 13, it is not blocked and you don't need to click the Red Icon.

Make sure that you have installed the 32 bit Java plugin.

I have the same problem

I have indeed installed the 32 bit Java 7 Update 13 and attempts to run either of those test pages also get the "Application has been blocked for security reasons" alert box instead of the Java warning message I got with Update 11, and there is no red Java icon in the URL box. That means that I can't enable the Java app, which is a satellite photo loop on my local National Weather Service web site.

It was working with Update 11. It appears that Mozilla 18.0.2 doesn't recognize Java 7 Update 13, which supposedly fixes the 0 day security problem of earlier Java 7 versions.

Is there an about:config or Windows registry setting fix for this problem?

That is just great except

that it updated again and blocked it again!

The Mozilla developers have decided to block all Java plugins because of ongoing security issues.

"The Mozilla developers have decided to block all Java plugins because of ongoing security issues."

Thanks, I'd rather make that decision myself. I only enable Java for the one site (a Federal government site, btw) that I use that requires it.

I really don't need for the Mozilla development team to start nannying me.
