This bug was filed from the Socorro interface and is report bp-b02dbe3c-72b1-4df2-964c-b54942160510. ============================================================= Reporting this as Firefox just crashed on me. I was writing a comment in a text field in Aha. I have many tabs open, including GDocs (although not doing anything with them at the time). I'm on a Windows 10 machine, X1 carbon touch. I'm running nightly, and I just checked - says I'm up to date (49.0a1 2016-05-10) I'm also not positive if I've added this to the right bugzilla component! The crash report gave me a few different options, so I've just chosen one!

So, it looks like FireWinEvent() is called on an accessible where IsProxy() returns true, but DocProxyWrapper() does not. That would seem to imply either Proxy() returned null, or Proxy()->Document() was null, but neither of those should ever happen.
low volume crash, 2 crashes on 57, all other are >=50
