Issue body
Snap version of firefox was working fine until until I checked the "Pre-released updates (bionic-proposed) and performed a system update. I am now running Ubuntu 18.04.4 with Unity desktop and kernel 5.4.0-37.41
Starting firefox from terminal results in the following error message:
~$ sudo snap run --trace-exec firefox
[sudo] password for mark:
mkdir: cannot create directory '/run/user/0': Permission denied
XPCOMGlueLoad error for file /snap/firefox/372/libxul.so:
libdbus-glib-1.so.2: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

I can start firefox by going into /snap/firefox/current and clicking on the firefox executable file. In fact as a workaround I created a firefox.desktop file shown below, but I suspect I am running in an unconfined manner by so doing...
#!/usr/bin/env xdg-open
