Accessibility and screen reader bug day

March 12 2013, 8am to 6pm Pacific Daylight Time, UTC-7

We will be focusing on screen reader bugs for this bugmaster day. We're inviting screen reader users, people with any sort of web accessibility need, and developers who work on a11y issues. Some of the Mozilla Accessibility team may join us in filing new bugs for Firefox (and Thunderbird), triaging, and trying to reproduce existing bugs. Since Bugzilla itself, and this wiki, may present problems for screen reader users, we can use the IRC channel to coordinate information and action.


What to do

  • Introduce yourself in the IRC channel
  • Make an account at https://bugzilla.mozilla.org
  • Chat with us about filing new bugs
  • File bugs!
  • Check existing bugs from the list below, and try to reproduce them
  • Add new information to existing bugs.

Filing new bugs

If you would like to file bugs you will need to have a bugzilla.mozilla.org account. If you aren't sure how to best describe the bug, join us in the irc channel to chat about it.

  • Make a bugzilla account.
  • Follow through with the account email.
  • Log in to bugzilla.mozilla.org.
  • Check that your bug isn't already in bugzilla. You may also want to check the support forums.
  • Enter a new bug for Firefox, Firefox for Android, or Thunderbird.
  • For other Mozilla product bugs, use the main enter bug page or ask on IRC for a direct link.

Improving bugs to make them more useful

To create a good bug report, or improve an existing one, please include as much detail as you can about the issue. Here are some possible details to include.

  • First, read the bug and try to understand it.
  • Detailed steps to reproduce the bug.
  • Hardware and software you're using
  • Urls that are affected.
  • Does the bug happen in other browsers?
  • Can you attach error logs or crash report id information from about:crash? ** More info: (How to use Mozilla Crash Reporter)
  • Can you attach a stack trace?

AccessFu mobile bug list

AccessFu is the Javascript, in-browser assistive technology that provides accessibility on Firefox Mobile, and in the future on Boot To Gecko.

  • AccessFu bugs (bugzilla search) There may be bugs in this list that can use triaging and may be obsolete, like for renaming stuff that doesn't exist. A good start would be to enable talkback on an android device, play with firefox, and see what accessfu is all about (eeejay)

Meta bugs

Bugs that collect many bug reports into one discussion. Read through a meta bug in an area of interest to you!

Here is one easy way to contribute. Do some searches in Bugzilla for bugs that are in the category of a particular meta bug. Then add those bugs as "Depends on" to the meta-bug, or add a comment to the meta bug with a list of bugs to be added.

Bugs we poked

  • 319431 Improvements for keyboard navigation for entering addresses. (Added to the tracking bug for Thunderbird accessibility.)

To Do

Thoughts on this bug day.

  • Plenty to learn here about this wiki's accessibility and Bugzilla accessibility.
  • Some of these issues may need cooperation between screen reader authors and Mozilla.


This is for notes on the bug day and reports on what we accomplished.
