This bug was filed from the Socorro interface and is 
report bp-b4e96646-c81c-4cb5-87bd-025c22170330.

Seen while looking at nightly crash data - these Mac crashes appear to have started around 20170328095415 in Nightly 55: There appear to be a few crashes before that, but more in the 55 nightly cycle.

One report says: Using voiceover just to move around the UI, but the URL appears to no longer be on github:
Not really enough bandwidth to jump on osx a11y issues (sadly) but if there is a quick fix we'll take it. Marco a nearby comment (in at the top of the stack) mentions bug 638465 and possibly this part of our code getting cleaned up if that one was fixed properly. Any recollection?

Unfortunately not. That bug is quite old, and I no longer remember what the specifics were. Even re-reading it doesn't jerk a memory now.

if this is with e10s I suppose it could be an issue where aAccessible is null and some more mac stuff needs to proxy some methods it isn't yet.

Low volume so too late for 56 I guess.
