The Web Developer extension adds various web developer tools to a browser. The extension is available for Firefox and Chrome, and will run on any platform that these browsers support including Windows, Mac OS X and Linux.

Works well in collaboration with Firebug and HTML Validator, offering some features that are not available in those developer browser extensions. Far too many tools to list them all, but some of our favorites we use often:

• View all JavaScript and/or Cookies related to a page
• Disable JavaScript and/or Cookies for testing
• Find Broken Images and Links
• Display Image Dimensions, Filesizes, and location
• Resize browser window to preview different resolutions
• Display browser window size
