By the way, this is the kiss of death query. MOZ_CRASH, start up, in safe mode. We’re basically forcing these people away. There is nothing they can do even if they really want to run Firefox (assuming this is a persistent start up crash, of course.) The numbers aren’t high, and majority of them are OOMs, but I still feel like this query should never have things in it. (Randomly picked 8 seconds, I know that some consider it a start up crash if it crashes much later than that.)
