The firefox desktop goes to black screen, no its not my computer. it seems to be whatever website i'm on it happens. and it effects any and all tabs being used.
I am using a brand new Dell XPS 13 9370 less then a week old. . Twice now I have left my machine unattended for a long period of time with the Firefox Quantum program on screen. The first time was for 30 minutes, and then second for 3 hours. When the machine resumes out of sleep mode the screen goes black and I am unable to use the machine and am forced to do a hard reset to restart the machine. I have a second monitor plugged in both times. an Insignia 32" flat screen TV that is several years old. One time the TV screen went black and I was able to recover by unplugging the screen before the problem migrated to the laptop screen. Since I have uninstalled the Firefox program this issue has not re-occurred and it has been three days.

Many have reported issues with Firefox running when the computer goes to sleep.
Is there a reason you leave the browser running? If not, shut it down before leaving.
