Now, I know that the be-all-end-all of JavaScript debuggers these days is Firebug, but sometimes I have to use Internet Explorer for my testing (like intranet pages with VBScript or ActiveX controls). I’ve always used the old Microsoft Script Debugger for such things — which isn’t even in the same league as Firebug, but at least it allows you to step through code and change variables and execute expressions on the fly.

In the last week or so, I’ve seen links to two very interesting other ways of debugging JavaScript in IE:

• Debug JavaScript with Visual Web Developer Express (via Simon Willison)
• Debug JavaScript with a Firebug Lite Bookmark (via Simon Brunning)

So, new toys to try…

UPDATE: I got some great suggestions in the comments so far, including:

• Matt White says that the script debugger that ships with Frontpage is a little better than the stock MS Script Debugger
• Ron Kats says that Windows Live Toolbar has a good debugger, although I didn’t see any information about it on the live.com site — I’d love to see some instructions on that, because now that Onfolio is integrated with the Live Toolbar I’d be willing to give it a try
• Carl Tyler uses DebugBar and likes it
