I've upgraded to firefox 79.0 last night. The first time I started the browser it begins to import my old data, but then it crashes and cause my phone to restart (Sony xperia z1c, ACIP 14.0, Android 9). After that, the phone starts to loop restarting every 2-3 minutes. It is clear to me that it is an underground process of firefox that it is causing that, because after having uninstalled firefox and replace it with an older version from my backup (68) everything is working fine again.
I've also tried to fresh install Firefox, by deleting it first and then installing it, but the same problem has happened.
Any idea how to solve this?
