The Web Developer Toolbar for Firefox is one of the tools I use most often when developing web sites. I've often wished there was an IE version for testing sites in IE. Microsoft has granted my wish—they now offer a Developer Toolbar for IE. It works on IE 6.0 and later, and includes the following features similar to the Firefox toolbar:

• View DOM: Opens a panel that allows viewing the DOM for the current page in a tree, similar to Firefox's DOM Inspector.

• Disable: Includes options to disable the cache, images, cookies, scripts, and IE's popup blocker.

• View: Displays class and ID information for page elements, link paths, tab indices, or access keys.

• Outline: Similar to my most-used feature on Firefox, outlines tables, DIVs, and other elements in pages.

• Validate: Pop-up links to various validation services.

• Images: Displays image dimensions and other details.

• Resize: Resizes the browser window to common sizes (800 x 600, etc.)

• Misc: Includes options to clear the cache for a domain, clear session cookies, etc.

• Show Ruler: Opens a pop-up ruler to measure page elements.

This toolbar has a way to go before it's as useful as the Firefox toolbar, but it's already a must-have tool for those of us who test sites in IE.
