I miss Firebug for one simple reason: It detached from the browser window as a singular window that provided developer functions to all of your browser tabs. In modern Firefox and Chrome, each tab has its own distinct developer tools panel that can be detached as a separate window for the operating system's window manager to handle.
Firebug's behavior was somewhat analogous to "MDI" in legacy GUI applications, in that a single window handled multiple views. The view switched with your browser's active tab.
The funny bit is that the stack of developer tool windows we end up with today is reminiscent of the stack of browser windows we had prior to the advent of tabbed browsing.
