Firebug definitely has it's ups and downs, but in no way can I believe the IE6 mention is anything other than linkbait (right near the end, he says he's moving to Webkit's debugger). The most common problem I've run into with Firebug is that Firefox stops loading CSS/JS files. I've never had this happen without Firebug open, but it may be a Firefox problem.
