I switched to Chrome as my main browser a while back after Firefox started updating every 10 minutes and never seemed to be as stable for me on OSX as it once was. With that switch the only thing I really missed was my beloved Firebug plugin. I slowly adjusted to Chrome Dev Tools but its taken some time to get used to the different interations. Today I stumbled on this post by Josh sharing a great presentation that I wished I had seen earlier.
Chrome Dev Tools is really impressive in many ways and I'll be using a bunch of these new techniques on a daily basis. I simply didn't know some of them were there before.
