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.
