A nice tip at the IEBlog reminded me of something I knew a long time ago, but forgot since I began doing most of my JavaScript development testing with Firefox. My favorite features in Firefox are those rich extensions that make debugging JS a pleasure and the fact that Firefox shows you exactly (file and line number) where your JS errors are. Turns out IE has had this for a while and the post Scripting Debugging in Internet Explorer show you how. Simply uncheck a couple of IE options and install the Microsoft Script Debugger and you are getting much closer to Firefox-style JS debugging!

Wow, blast from the past! I’m in the same boat as you, where it’s been so long since using IE as my main dev. environment that I’ve forgotten that trick….
It’s worth pointing out that in addition to the Script Debugger that you’ve mentioned, if you have Visual Studio installed it will open the debugging environment in Visual Studio. (only the Express editions are free, though)
Be warned, I’ve already found that the above mentioned script debugger DOES NOT work with IE7′s current beta release..
Does anyone know a good javascript debugger for ie7 ?
