[nfbcs] My Opinion and Experiences with Accessibility

Hi.

In my experience, Firefox is quite accessible with Jaws, and
especially with NVDA.  So, why not support it for accessibility?

Based on anecdotal evidence, and the WebAIM surveys, I am confident
that the majority of screen reader users are using Internet Explorer.
That being said, I personally prefer and use Firefox with Jaws and
NVDA.  It also appears that NVDA users are much more likely than Jaws
users to use Firefox, which is why we added support for that browser
when we added NVDA support.

However, since I do a lot of the accessibility testing, and implement
many of the fixes, I've always tried to ensure things work with
Firefox as well, even when we didn't officially support it.  Most of
the time, it wasn't too difficult to pull off.
