I'm using MacOSX 10.5.8 and the default Java provided by Apple (e.g. /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java). My web browser is Firefox 3.6.12.

I'd like to view the Java console to debug some Java applets which I access with Firefox.

How can I enable the Java console?

This is not done via any Firefox configuration option, but an account wide Java setting:

Open the Java Preferences utility which you can find in Applications -> Utilities.

There, under the Advanced tab, and "Java console", choose "Show console". alt text

I have tried this, and I still do not see a console. I believe that the console may be active, but does not automatically become visible when I open a Java applet. – Stefan Lasiewski Nov 19 '10 at 19:30
Well, eventually this did work. I had to change "Run applets:" back to the default "Within Browser Process', and now the console works. I did try both options before, and neither worked. – Stefan Lasiewski Nov 19 '10 at 20:56
Ah, I didn't know about the "Run applets" setting, but glad you got it working :) – Jonik Nov 20 '10 at 3:03
