Hello! I tried searching for a regression range on Ubuntu 18.04 and I found out next scenarios:

• 79.0b1 Firefox snap build is restarting as expected if permissions are changed while running
• 80.0b1 Firefox snap build is crashing when trying to restart after changing permissions giving a readable Crash Reporter link
  Pushlog: link.

This readable crash message can be seen until 84.0b8 included. Starting with 85.0b1 snap this message is displayed instead: link
