This is driving me crazy! When FF 12 came out, Firefox's own 'Inspect Element' button on the right-click menu took the place of there the Firebug 'Inspect Element' button used to be.
As I've been doing web development in Firefox forever, my muscle memory still clicks there when I want to use Firebug.
Is there any way to remove the Firefox internal 'Inspect Element' and replace the button on the menu with Firebug's, returning it to its original position (marked NO
in the screenshot)?
