Plugins provide extended functionality not native to the browswer. Examples include PDF, Flash, Shockwave, Silverlight, and Java.

Anytime a plugin is used on a page, they must be tested for accessiblity.

Pro-tip: Flash always fails for accessibility but is often given an exception.

Testing

  1. Identify any plugins on the page.
  2. Identify a link to download each plugin.
  3. Check each plugin for accessibility.
