ARIA Validator

Adds a button to Chrome that you can click when you want to validate the ARIA implementation of the HTML page you are viewing. Also checks for duplicate IDs in your HTML.

It will open a new tab showing errors and warnings for each frame it can read on the page.

Note: you may have to reload open tabs after installing this extension before it will function on them.

Disclaimers:
1. This is beta software.
2. It will not find ALL issues.
3. You should use this tool to help you avoid simple mistakes when implementing ARIA.
