Welcome to the W15yQC - Web Accessibility Quick Check Firefox Extension Website

The W15yQC Firefox Extension is a tool web developers and web accessibility professionals can use to quickly check a dynamically generated web page, automatically scan a website, for common web accessibility issues.

Why 'W15y'?

The '15' in 'W15y' stands for the number of letters between the first W and last y in 'Web Accessibility', making W15y an abbreviation for Web Accessibility. This is in the same vein as using 'a11y' as an abbreviation for Accessibility and 'i18n' as an abbreviation for Internationalization.
