I accidentally pressed command+y (wanted to press command+t) and Nightly crashed. How to reproduce it: I had just logged in into gmail account and in the left corner there was notification if i want to remember password or not (i think this is important because on any other tab i tried it did not crashed). Then I pressed command+y and it crashed. https://crash-stats.mozilla.com/report/index/5447ecd3-fa4b-4037-9da9-518a02150226 I am not sure in which component to put this bug.

Thanks for your report. We're working on it.
