Did you find any better feature in IE 8 Developer than firebug?

Doe开发者_如何学Pythons IE 8 Developer toolbar have something better than firebug ? How to use IE 8 Developer toolbar in a way like we use firebug in firefox.? Is there any good tutorial on "how to take good use of IE 8 Developer toolbar"?

If you're looking for something that mimics firebug in IE (your question is unclear), then there is Firebug Lite. If you're looking for a resource for learning about the IE8 Developer Toolbar there is this article and a number of other articles available via simple searches.

edit: got a more up-to-date link for the Dev Toolbar article

While the IE Developer's ToolBar, which was an addon for IE<8 and has been integrated into IE>8, is tightly integrated into IE and has it's own unique benefits for debugging IE specific issues, I find Firebug to be more conducive to general debugging scenarios.

That is my take on the first of your THREE questions ;-)

I will leave the rest to others.
