Accessibility Inspector

This tool provides a way to access important information which is generally exposed to the assistive tech stack on the current view page via the accessibility tree present. It allows checking what element is missing or otherwise needs attention. 

Accessibility is the practice of creating websites usable by as many of us, as much as possible. This tool tries the best to not prevent anyone from accessing information due to any kind of disability. Disability also includes any feature that a user is not able to use due to the lack of capabilities of the device which is being used to access the site. This may include the speed of their network connection, or their geographic location or locale.
