IE Developer Toolbar does not work
The IE Developer Toolbar is similar to Firebug for Firefox. It provides you with a set of tools for troubleshooting pages efficiently (helps a whole lot with those positioning/css issues).
Downloading and installing the toolbar is straightforward and works without a hitch. However, when I tried to use it, It would never work. I tried installing/uninstalling a couple of times with no luck. Clicking on the IE Developer toolbar icon does nothing and if you reach it via the menu Tools-Toolbars-Explorer Bar->IE Developer toolbar, it brings up the toolbar which does not help you in any manner.

After a little hunting around I found that the reason it does not work is because 3rd party extensions are not enabled.
This can be enabled via ‘Tools->Internet Options->Advanced->Browsing->Enable third-party browser extensions’. Check that, apply your changes and restart IE. The toolbar should now show up with the DOM elements and their corresponding styles and attributes.
Its a good tool to have at your disposal.

On windows 7 the IE developer tools menu item shows under tools but the window does not show
Any Idea how to make it work?
@Ofer,
I’m just wondering if the same third party extension enabling needs to be done under IE 7. But I have not faced that problem with IE7 so far. It seems to work out of the box.
Afraid it does not work for me. I checked my advanced settings and the Enable third party browser extensions is already checked. Anyone have other suggestions?
