Web developer tools help developers implement standards, and thus increase the accessibility of sites they develop.

• Firebug (free): This Firefox extension analyzes a page's HTML, CSS, and JavaScript and provides the file name, line number, and a brief explanation for each coding error.
  

• Firefox Web Developer Toolbar (free): This Firefox extension allows developers to test a site by turning off CSS, JavaScript, and pictures, which shows how a screen reader would get through a site. WebAIM has an article on using the Firefox toolbar to check for accessibility.
