I crashed acessing gmail.com
BTW, I got two crash reports listed in about:crashes for the same crash. Is that correct?

This has risen to the #1 overall top browser crash on nightly - adding top crash keyword.

Comment 3

[Szmozsánszky István [:flaki]]

This now consistently crashes nightly on "https://mail.google.com/mail/u/0/", which is my @mozilla.com e-mail address, logged in, right before the loading bar reaches 100% and before any of the inbox is shown. This does not seem to creash on the homepage (login screen) though.

[@ mozilla::a11y::NotificationController::WillRefresh] is also showing up in crash stats as starting with 20170109030209.

[Marco Zehe (:MarcoZ)]

I am also seeing this crash whenever I start Nightly, and Gmail is the first tab loading, or I switch to the Gmail tab and it needs to load. Only in E10S mode. NVDA is running.

Gmail craches always. 
Youtube also crashes sometimes.

Backed out from 53 in bug 1184217. tomcat retriggered a new nightly build already.
