Revolutionary in what way? What could you do in Chrome Dev Tools when it first came out that you couldn't do in Firebug at the same time?

I think revolutionary as how Apple defines the word. They weren't the first but they sure had the panels running the smoothest.

That makes no sense, GP stated the chrome devtools were just as revolutionary as firebug was when it first came out. Not just "meaninglessly revolutionary" but more revolutionary than the one tool at the origin of all modern web devtools.

I don't remember precisely the feature set of Chrome devtools in intial version. I should have clarified. The current iteration of Chrome Devtools compared to firebug represents a revolution in web debugging capability

Boy, I missed the time when we used "revolutionary" for, you know, revolutionary things.

Wasn't the initial version of the Chrome dev tools just the exact same as the Apple WebKit/Safari dev tools until Google started fleshing them out? Or am I misremembering history?
