This free extension does a great job in identifying accessibility issues that can be checked in an automated fashion. Each error is provided with references to the code and tips on how to address the problem as well as links to WCAG information. I was using the free version since 2018. If you pay for their Pro version of the tool (which I have since 2023), additional helpful features are available. You can save a page's test results on the web and share it with collaborators who are involved with fixing the problems. You can also export the list of issues to an external file if desired. A nice feature of the pro version is their Guided Tests addition. These tests are beneficial for those who don't know a lot about accessibility manual testing and they help guide you in identifying other problems related specifically with respect to tables, forms, keyboard navigation, and more. I've tried other extensions which don't compare in the way feedback is presented. And those other tools don't seem to identify as many issues as DevTools identifies.

Looks like it would be useful, but the free version doesn't currently let you select WCAG 2.2AA, which is the standard being expected by the UK GDS for Public Sector websites since October 2024. https://www.gov.uk/guidance/accessibility-requirements-for-public-sector-websites-and-apps#meeting-accessibility-requirements

Just hope it can support WCAG 2.2 sooner! Very handy tool to use.
