Always crashing with segmentation fault after update to 63.0
Since I updated to 63.0, firefox always crashes some seconds after I started it. Within the few seconds until the crash firefox seems to work just as normal. When I start it from terminal it outputs "Segmentation fault (core dumped)" as soon as it crashes. It worked perfectly before the update. It crashes both on my Ubuntu and on my Arch Linux machine. Those are using the same profile, but the Arch machine uses an older version of the profile. It does not crash when I start firefox in safe mode. So I disabled all extensions, and started it in normal mode, but that still crashes.
So I guess the new version can't cope with some parts of my profile.
I'd be glad if anyone could help me somehow.
