Back in early days, Firefox used to have a simple DOM Inspector, which was later removed in Firefox 3 and made available as add-on.
Well, for the upcoming Firefox 4 release, Mozilla is planning to bring such tool back and make it a part of web browser again.
While Web Inspector is not intended to replace Firebug, it can be used for basic tasks, such as: elements identification or site structure overview.
