Firebug was amazing, it was way ahead of what Chrome had when it was released!

Dedicated work on Chrome DevTools started only in 2009 and before version 3 or 4 Chrome had only had Elements panel inherited from Web Inspector, Console and gdb-style command line debugger (perhaps basic Network don't remember). It was catching up with Firebug quickly though because web developer tools was stated as a priority for the project.
