This free Firefox add-on lets you test a Web site's accessibility with the click of your mouse. But it's really not a stand-alone program; rather, its a direct link to the TAW Web site.
TAW3 With A Click can be accessed four ways: from your Tools menu, with a hot-key combo, by right-clicking, or by clicking the status bar icon. You can opt to open the report page in another tab, or in the current tab. Web sites are assessed using W3C Web-Content Accessibility Guidelines. We were able to choose from three accessibility levels when checking a page. Each time we ran the program, the report page quickly appeared in a new tab. The accessibility tags appeared on the new page, and a more detailed report, including any errors, can be found by scrolling to the bottom of the page.
TAW3 keeps a low profile while you're browsing, and if you're a Web developer, it will save you a couple of steps.
TAW3 With A Click toolbar allows you to verify, with just a click, the accessibility of the Web sites that you are visiting, by means of the TAW3 online service (www.tawdis.net). It makes use of the W3C Web Content Accessibility Guidelines (WCAG 1.0). This version is the first release on CNET Download.com.
