Re-Enable about:config Warning in Firefox 3 - Guide

Restoring the about:config Warning in Firefox 3

Users who have customized Firefox 3 may have previously dismissed the warning message regarding modifications to advanced settings. While disabling this message allows for unrestricted configuration, there are scenarios where its re-enablement is desirable.

For instance, if Firefox has been tailored for another user, restoring the warning can help prevent unintended alterations to the browser's configuration.

How to Re-Activate the Warning

To re-enable the about:config warning, begin by entering "about:config" into the browser's address bar. This will access Firefox's advanced settings.

Next, utilize the filter function to locate the following preference:

general.warnOnAboutConfig

This preference controls the display of the warning message.

Simply double-click on the "general.warnOnAboutConfig" entry. This action will toggle its value back to "true".

Upon completion, the warning message will reappear whenever you attempt to access or modify settings within the about:config interface.

This ensures that users are cautioned before making potentially disruptive changes to Firefox's internal settings.
