This guide will tell a Firefox enthusiast how to disable the “Here be dragons!” warning screen that appears when you enter the URL “about:config”. Disabling this warning will save time and provide convenience for a Firefox user who is interested in changing the look, feel or performance of their Firefox browser. Read below to find out how easy it is to remove this pesky and unnecessary warning screen and get on with your configuration editing.

Firstly you will need to type "about:config” into your address bar of Firefox and then click the “I’ll be careful, I promise!” button on the “Here be dragons!” Warning page. Once you have done this and you are fronted with the list of values in the configuration page, you will need to enter “general.WarnOnAboutConfig” into the “Filter” bar at the top of the page.

 

Once you have entered the text into the Filter bar of the about:config page you will be left with a single value. The value will of course be: “general.WarnOnAboutConfig” and will be set to “true”, unless of course you have already disabled the warning message.

 

To disable the warning message until you decide to re-enable it is as simple as setting this value to “false”. Once you have changed the value to false you will notice that from now, until you re-enable the value; you will be fronted directly with the configuration page as opposed to the warning page upon entering “about:config” into your address bar.

It is that simple to disable that irritating warning message that slows down your configuration editing. Enjoy your newfound Firefox configuration editing knowledge.
