Web developer tools

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.
