i resisted switching to chrome for months because i thought the chrome inspector was inferior to firebug, but i got used to it after forcing myself to switch primarily to chrome. now i find it's actually superior in many ways.
Indeed. Little things like proper emacs keybindings in the JS terminal (Ctrl-P for previous line = lifesaver!) make Chrome's inspector preferable. Haven't needed to go back except for the YSlow/Firebug integration [probably a Chrome plugin for that as well].
Actually FireBug sucks for inspecting elements. I prefer Chrome and Stylizer (CSS). FireBug is good in JavaScript (very good) and the browsing of the DOM. I like it.
