Changes

Accessibility overlays for websites may be called by different names such as plugins, apps, software, and toolbars. They are marketed as a complete solution for accessibility. Unfortunately, this is not true. An overlay on your system or a public website will not make your system accessible or compliant. An overlay is not a substitute for good design, content, coding, or testing. Some people argue that overlays (toolbars) in and of themselves are discriminatory. Other vendors have created plugins to disable these overlays. People with disabilities find overlays annoying as they effect performance and have the opposite effect of what is intended.
