Our extension allows you to check web pages or entire sites as you browse. Requires separate application (see below).

The range of tests includes: Accessibility (WCAG 2.0-2.2, US-508, ARIA 1.2), HTML (over 20 standards, including the latest HTML5), CSS (over 60 different specifications) , a broken links checker, and a multi-language spell checker.

It works in combination with a copy of the Total Validator application, which must be installed and running.

Go to our website to download either our free Test application (one page validation results), or upgrade to Total Validator Basic (test one page at a time)  or Total Validator Pro (fully featured for testing entire websites).
