I use Macbook Pro 15 with Sierra 10.12 and Firefox 50.1. Since installing Firefox (two weeks ago), every time I open the Macbook's lid and wake up the system, I see the Firefox crash reporter. I checked my Firefox, add-ons and OS to see if they are updated, I disabled unnecessary add-ons, I restarted the Firefox in safe-mode; none of them solved the problem. The only help that they did was by doing so, the Firefox crashed not at every system wake-up, but by a random time (sometimes after one hour sleeps, sometimes 6 hours). Firefox hasn't had crashes during the time I used the system, it crashes just at the system wake-ups (and I noticed in console that it is not due to the system wake-up itself, but due to some errors after couple of hours) Any help would be appreciated. My crash-id is bp-2024233a-bafe-485c-9ba0-a68fe2170108
