[David Poehlman]

I am happy to report that on:

https://wiki.mozilla.org/Mac:Accessibility
"Note! This page has been reported to cause Safari to crash, if  
VoiceOver on. The bug has been reported to Apple as RADAR #4534388. To  
avoid the crash, turn off VoiceOver or try another browser." no longer  
applies.
