Does the XUL cache still exist?

I was looking at the following article - http://blog.mozilla.org/addons/2009/01/28/how-to-develop-a-firefox-extension/ - as I would like to play around with developing an extension. The article recommends disabling XUL caching with the following option in about:config - nglayout.debug.disable_xul_cache = true

This option does not appear to be available to me. Is this is an error, or is XUL caching not used anymore, or do I need to go elsewhere to disable it?

I am on version 19.0.2, and the OS is Ubuntu 12.10

Sure, you can see that in the source code.

That's great thanks. I am still slightly unclear as to whether I can still turn it on and off as I wish though, if you could clarify that it would be superb.

You're welcome.

Some pref are hidden by default and do not show on the about:config page.
Once you create such a pref then the pref remains visible on the about:config page and can be modified at any time.
If you reset such a hidden pref to the default value then this pref will be removed on the next start of Firefox.
