I have a moto z3 and I installed Firefox to use as my browser and it's something I've used for a long time but whenever Firefox's crash report pops up my phone only shows a blank screen and it's stubbornly tries to stay there. I have to hit the return to home screen button to get rid of it. If I hit the other apps button it immediately pops back up and it usually pops back up several times when I try to hit the home button. I usually don't care about this but recently it started popping up when my phone is off and when it pops up when my phone is off you can interfere with apps like my alarm which is almost made me late for work several times now.
