Accessibility and Mozilla 编辑

Accessibility is the idea that software (among other things) should be designed to be usable and, as much as possible, convenient to use for people with disabilities. Mozilla strives to make its software accessible; the documents below cover the ways in which we do so. These articles provide Mozilla-specific details about accessibility.

Accessibility API cross-reference

This cross-reference helps us see the difference between today's accessibility API's. All accessibility APIs to date define a list of possible object roles, or general types, such as button, menu item, text, etc. They also define a list of possible object states, such as focused, read-only, checked, etc.

Accessibility Features in Firefox

Firefox works with popular screen readers, with the best support currently coming from GW Micro's Window-Eyes 5.5. We are optimistic that JAWS support will catch up this year. In recent articles from both AFB's Access World and NFB's Voice of the Nation's Blind, reviewers found no significant roadblocks in moving to Firefox from Internet Explorer for screen reader users. In fact, the same keyboard commands are still available, so users can become comfortable and productive right away.

Accessibility Information for Core Gecko Developers

Both end users and developers are invited for discussion on the live IRC channel at irc.mozilla.org/#accessibility. Since this is a worldwide effort, there is always a good chance to find someone to chat with there, day or night.

Accessibility information for UI designers and developers

When you design user interfaces with accessibility in mind, they will work for more people. This page describes a number of design-related aspects to look out for, in no particular order.

Accessibility/LiveRegionDevGuide

This page is currently under construction. This developer's guide lays out general guidelines that assistive technology (AT) developers can use in developing live region support. This guide was written from an ATK/AT-SPI point of view as part of the Orca Live Region Support project. However, many of the concepts were also used during the development of FireVox, an AT using IAccessible2.

CSUN Firefox Materials

Firefox 1.5 is a fast, free, standards compliant web browser which is rapidly gaining recognition for its fresh, streamlined approach to browsing the web. In addition to winning major awards such as PC World Product of the Year, Firefox has attracted a huge following among savvy users who simply care enough about their web browsing experience to download a new piece of software. Websites such as online magazines with sophisticated audiences are now reporting upwards of 25% Firefox usage.

Mozilla Plugin Accessibility

Plugins in Gecko-based browsers have a lot of accessibility issues. Here is a rundown of problems and the planned solutions:

Mozilla's Section 508 Compliance

Mozilla’s UAAG evaluation report

The UAAG document contains a very rich set of accessibility guidelines, that broadly define how accessibility should be implemented by any user agent, i.e. software that renders web content. The UAAG is not the basis for any government accessibility regulations at this time.

Multiprocess on Windows

A high-level overview of the ideas behind the a11y+e10s design is available on the wiki.

Software accessibility: Where are we today?

The accessibility of computer software has seen drastic improvements over the past two decades. This article reviews the progress and technology as it has developed.
