…cannot be done with the built in dev tools, as I reminded myself today. I guess my memory painted a fonder picture of the first version of the IE debugger than it deserved. I’ve been using the IE8 debugger a lot of late as I’m working on a very JS heavy UI targeted primarily at IE users, which has some firebug-esque features, like break points/ profiling etc and I foolishly assumed such things were always there, because a web debugger without these tools wouldn’t be much use..
Anyway turns out all is not lost- after wading through a bunch of rubbish solutions I eventually found an awesome profiler (for free, of course!) which works with IE 6, 7 & 8! Check it out- “DynaTrace AJAX Edition“
