287214 - Crash at dujobs.org when screen reader is running

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Aaron Leventhal]

1. Load screen reader
2. Load www.dujobs.org
3. Crash

What seems to be happening is that there is a brief "One moment please ..."
message that appears and then disappears as dujobs.org loads. Before Window-Eyes
is finished parsing the mini  page with that message, the real page loads and
the old mini-message page goes away. Window-Eyes is still quite reasonably
asking for information on the old page, but it is gone, and Firefox doesn't
handle that gracefully.

Another fact that doesn't seem to help is that we act as if the new page is
finished loading while it is still just transferring.
