> Firebug allows you to do that.
Please please tell me how to do this. I want the "Web Developer" menu gone. I want Firebug as a first-class entry in the Tools menu again. And while you're at it, it would be really nice to have "View Source" and "View Page Info" in the View menu again.
Perhaps I'm a little bitter, considering I saw the DOM Inspector ripped out of Firefox, relegated to Firebug, kicked around, and now that Firebug is awesome, I see weird versions of a Firebug subset getting in the way. Why couldn't it be part of the browser, and why not just put Firebug in the browser if you want it back in?
