Web Accessibility Resources

The following are online free web accessibility tools and resources. Not all reports and validators are the same. I recommend you test your site’s various pages with at least five of these to get a better sense of what needs improvement and what passes the tests.

Accessibility Online Checks, Tests, and Validators

Accessibility Guidelines, Regulations, and Policies

Vision and Color

Accessibility Emulators

Firefox Extensions and Tools for Accessibility

Firefox has the Access Firefox team working overtime to ensure Firefox complies with web standards but also helping to support and promote accessibility extensions in Firefox. The following is a list of many of those tools which include accessibility assists, emulators, validators, and more. Not all of these may work with the latest version of Firefox, and newer alternatives may be available, so check Access Firefox and the Firefox Extensions List for updates.
