Information about using the Web Developer Toolbar

Headings Map Add-on for Firefox

The Headings Map extension permits you to easily see and assess how headings are used on a page so that you can be sure they are being used to convey meaningful structure.

WAVE Toolbar

The WAVE Firefox toolbar provides a mechanism for running WAVE reports directly within Firefox. Because the toolbar runs reports entirely within your web browser, no information is sent to the WAVE server. This ensures 100% private and secure accessibility reporting. The toolbar can check intranet, password-protected, dynamically generated, or sensitive web pages. Also, because the WAVE toolbar evaluates the rendered version of your page, locally displayed styles and dynamically-generated content from scripts or AJAX can be evaluated.

Accessibility Firebug Wiki

If you already use Firebug, you may find this accessibility extension to be helpful since you will be able to incorporate it into your current work environment. Skimming through the Wiki documentation will give you a sense of how it works, before you install it.

AInspector Sidebar

AInspector Sidebar evaluates the accessibility compliance of web pages based on WCAG 2.0 requirements using OpenAjax Alliance rulesets. It organizes the evaluation results by Rule Categories and WCAG Guidelines.

Worldspace FireEyes

Worldspace FireEyes is a web accessibility tool that ensures both static and dynamic content within a web portfolio are compliant with standards such as Section 508, WCAG 1.0, and WCAG 2.0.

Juicy Studio Accessibility Toolbar

This Toolbar contains both a Color Contrast evaluator and a Complex Table Inspector. Right-click functionality allows for reporting of these issues.

Tanaguru Contrast-Finder

This addon allows you to select colors on a page and check contrast.

WCAG Contrast Checker

This addon allows you to enter HEX or RGB foreground and background values to check contrast.

Firefox Landmark Extension

The Firefox Landmark Extension, currently hosted on GitHub, will enable you to see whether, and how, ARIA landmarks have been implemented on a page. Using landmarks correctly will help screen reader users (and perhaps users of other assistive technologies, in the future), navigate your site consistently and effectively.

HTML Validator (based on Tidy)

HTML Validator is a Mozilla extension that adds HTML validation to Firefox and Mozilla. The number of errors of an HTML page is seen on the form of an icon in the status bar when browsing. You see the details of the errors when looking at the HTML source of the page. You can "view source" to see errors highlighted, and you can use Tidy to fix them.

Mouseless Browsing

Mouseless Browsing (MLB) means id-based browsing. The major goal of this extension is to enable browsing only by using the numpad keys. Mouseless browsing is based on marking all links, form elements and frames with ids. You can then trigger an action (e.g. following the link) by simply entering the id and depending on the configuration confirming it by pressing Enter.

Longdesc

Adds "View Image Longdesc: ..." to the image context menu (obviously only if the image element does have a longdesc attribute set).

Screen reader Simulator

"This addon allows you to activate Firefox's integrated mobile screen reader on desktop browsers. You can test web content and see how a blind user would interact with an app if they accessed it on a mobile browser." It does not provide all of the functionality you could obtain by testing with computer-based screen readers, such as NVDA (free for the PC) or VoiceOver (free for the Mac), but it can give you a sense of how your site might work.
