About this extension
AInspector for Firefox evaluates the accessibility compliance of web pages based on WCAG 2.0, WCAG 2.1 or WCAG 2.2 Level A and AA requirements using OpenA11y Evaluation Library. There is at least one rule in the evaluation library for each Level A and AA requirement. It organizes the evaluation results by Rule Categories and WCAG Guidelines. Evaluation results can be exported in CSV or JSON formats. The tool is designed to help people learn about accessibility requirements, web accessibility standards and the best practices to make website more usable by people with disabilities. Web accessibility standards include the W3C Web Content Accessibility Guidelines Accessible Rich Internet Application (ARIA) specification and the ARIA in HTML specification.

NOTE: The extension does NOT collect any user or evaluation information or require a login for operation.
