288499 - Message bar buttons need accesskeys to be usable for screen reader users

Status: VERIFIED DUPLICATE of bug 287739

(Firefox :: Disability Access, defect, P3)

Description

[Aaron Leventhal]

When an alert popups up in the browser message bar, a screen reader user will
hear the alert -- something like
"To protect your computer, Firefox has prevented this site (foo.com) from
installing software on your computer ... Button Edit Options"

At that point the screen reader user is somewhere in the middle of the page and
has heard the alert, but don't know where it is on the screen or how to navigate
there. Adding an accesskey to the Edit Options button would solve the problem.

I suggest two possible solutions:
1. the browser.xml method showMessage() take another argument for the accesskey
2. that the showMessage()'s aButtonLabel parameter be able to take a label with
an & before the letter that defines the accesskey "Edit &Options"

Here are the button labels that need changing, that I know of:
missingpluginsMessage.button.label
xpinstallWarningButton
popupWarningButton when it is checked in from bug 220626
