Firebug for Internet Explorer

For a Firebug-like add-in to IE6 and 7, you can install Microsoft's Internet Explorer Developer Toolbar. The Firebug add-in for the Firefox browser helps in understanding and fine-tuning complex web pages, even those presented by Drupal and other content management systems. Installing the Developer Toolbar for IE provides similar features. Here is the page for this tool: http://www.microsoft.com/downloads/details.aspx?FamilyID=e59c3964-672d-4... There is also a "firebug lite" for IE, which we haven't used, and traces some but not all elements of a page.

Not even close

Based on my experience, the IE Developer Toolbar is just not in the same league as Firebug. Last I checked, it doesn't allow you to modify or add style properties. This capability makes Firebug really useful for theming sites or diagnosing display problems. It doesn't have the community support that Firebug does. The best example of this is the Drupal for Firebug module, which even allows you to run PHP code. The user interface is not as nimble either. And forget debugging JavaScript. On the other hand, I haven't experimented with it in IE8, so perhaps it has improved since then.
