The testcase doesn't seem to crash online.

I cannot reproduce it all. Stack is not clear enough.

The testcase seems to crash on reload. This is on MacOS10.9.3, btw.

Sorry, this should crash online, after the SpecialPowers extension was installed (which makes accessibility turn on with the testcase). The testcase now automatically reloads and should crash on reload after 1s.

aContext is hanging document accessible (not bound to parent document yet) and thus it doesn't have a parent. I don't think we allow cross document tables so it doesn't make sense to wait for document binding before we update it.

Comment on attachment 8453250 [details] [diff] [review] patch > Accessible* table = aContext->IsTable() ? > aContext : >- (aContext->Parent()->IsTable() ? aContext->Parent() : nullptr); >+ (aContext->Parent() && aContext->Parent()->IsTable() ? >+ aContext->Parent() : nullptr); this nested ? thing is kind of rediculous, use an if?
