Started a new contract the other day, and one of the folks I'm working with asked me what the deal is with my browser (I use Chrome to hold documentation / collab tools) - everybody else simply uses Firefox for everything. I can't stand how slow FF is for general browsing, but I cannot give up Firebug for the work I do.
Best part? Not the CSS editing, and not the JavaScript debugger (although that's really handy too) - truly the most useful features are the DOM inspector (easier to do that than look up some rarely-used property in the ref specs) combined with the console (test out a one-off bit of idea before fleshing it out and integrating it into the actual codebase).
I have recently been using the latest webkit nightly for all of my debugging. It's developer inspector is getting fairly close to firebug in terms of useful-ness. There are a few instances where it can't quite jump into the code as well as firebug but its getting there.
