I know Firebug is the standard, but I find myself using Chrome a lot (screen space, speed, etc.) Anyway, I think their inspector is pretty good, too. Certainly good enough that I don't want to fire up FF and navigate thru a site every time that I want to take a peak at the DOM.
However, probably the most annoying part is that I can't dock the Chrome inspector to the bottom of Chrome. I see that there's a dock button, but it doesn't seem to do anything.
Any tips? suggestions? Is it supposed to do something else? Thanks.
