[Bug 1799483] [NEW] Firefox blank screen; doesn't work

[Michael Weimann]

Public bug reported:

The repository version of Firefox only shows a white screen for me.

When starting in console it shows some errors:
Gtk-WARNING **: 16:36:55.427: cannot open display: :1
[Parent 25961, Gecko_IOThread] WARNING: pipe error: Broken pipe: file /build/firefox-MtV3KQ/firefox-63.0+build1/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 729
###!!! [Parent][MessageChannel] Error: (msgtype=0x30000B,name=PContent::Msg_InitRendering) Channel error: cannot send/recv

I'm using the Ubuntu desktop with Xorg (not Wayland).

Things I already tried out:
* starting in safe mode
* setting the DISPLAY variable

Using the snap version works. But I need the repo version...
