I use Firebug and the Mozilla JS console heavily, but every now and then I run into an IE-only JavaScript bug, which is really hard to locate (ex: *error on line 724*, when the source HTML only has 200 lines). I would love to have a lightweight JS tool (*a la* firebug) for Internet Explorer, something I can install in seconds on a client's PC if I run into an error and then uninstall. Some Microsoft tools take some serious download and configuration time. Any ideas?
