try starting firefox normaly with xwayland, close it and open it again 

have you built in wayland support?
because only nightly 65 and up supports wayland

Yes, I'm using 65.0a1 (2018-11-16) (64-bit). It starts fine with xwayland. But when I force it to use wayland backend, it fails to start.

what distro do you use?

I'm using Arch and when I install it fresh and try using wayland it hangs/doesn't open a window,
although it starts firefox-bin.
When i kill the process and start it normally (xwayland) it opens fine.
after that i can close the browser and open it again via terminal or changed .desktop file with wayland backend and it popens fine.

I'm using Archlinux with SwayWM.

I was able to get it to start using wayland backend by blowing away the preferences folder (~/.mozilla)

Spoke too soon. The problem is back. Now I can't start firefox-nightly again with wayland backend.

I get the exact same error on fully up-to-date Fedora 29 / Gnome.

Infrequently, Firefox will start on pure Wayland, run for several minutes, then hang. But almost every time, it fails to start as Jonny Mako describes in the top post.

Can you please run firefox as "WAYLAND_DEBUG=1 GDK_BACKEND=wayland firefox" on terminal and see when the hangout happens? Also please attach the wayland debug output and state where the hang happens in the log. Thanks.
