There's not much that the built-in Chrome Developer Tools can't do that Firebug can. Either way, Firebug is still an amazing plug-in.

Comment by jbuberel

One problem with Firebug is that when the page URL changes, the Net logging console resets/clears, giving you no ability to see what just happened if the page does an HTTP redirect. There are plans to fix this in version 1.5 of Firebug, but for now you're left with using Wireshark instead.
