  • OzART CSS and Table Inspector (Firefox). The “CSS off” tool checks for any visibility:hidden or aria-hidden=true elements, notes them, and then strips all CSS from the page. It then sets visibility:hidden on those noted elements from the first step. This provides an approximation of what a screen reader user will encounter. The table inspector finds any tables in the page. It changes the styling so that it is easy to identify TH and TD cells. It also highlights related cells on mouse hover, and provides cell information (e.g., the list of HEADERS) on mouse click. Please note that this
  • Chris Pederick’s Web Developer Toolbar – be careful using the Disable CSS styles as it also disabled display:none which is ignored by screen readers. (Chrome, FireFox, Opera)
  • WAVE toolbar (Chrome)
  • The Paciello Group’s Web Accessibility Toolbar (IE)
  • Deque’s aXe extension (Chrome and Firefox)
  • Chrome’s Accessibility Developer Tools (Chrome) – adds an “Accessibility” panel to the inspect mode, which shows you all the accessibility-related things on the selected element.
  • AInspector Sidebar (Firefox)
  • University of Illinois’ Accessibility Bookmarklets (Chrome, Firefox, Safari, Opera, IE 9+)
  • ChromeLens
  • Funkify
