I’ve finally found an equivalent to Firebug for Internet Explorer that actually works. I’ve been having limited success with the MS Script Editor and Visual Studio, specifically I have to deattach/reattach the debugger after every script error!
Surprisingly considering how much I’ve googled this, I never found
Nikhil Kothari’s Web Development Helper until it was recently mentioned on the ieblog. I suspect the problems I’ve been having are related to me running as limited user account on XP, with things locked down fairly well. So I still need to Runas… an administrator on Internet Explorer to use this extension, but that’s just one elevated process and it works great 
Hi Matt,
Could you tell me where is the firebug equivalent in IE?
