Public bug reported:
Firefox takes ages to start in a fresh desktop session, complaining
about timeouts on org.freedesktop.portal.Desktop, while the desktop
environment prompts me to kill it because it's waiting on its UI thread.
It spews the following on its stdout/stderr (some strings are in French,
sorry, mostly saying "error calling $foo: timed out"):
update.go:85: cannot change mount namespace according to change mount
(/var/lib/snapd/hostfs/usr/local/share/doc /usr/local/share/doc none bind,ro 0
0): cannot open directory "/usr/local/share": permission denied

I'm attaching my session logs.
It could be related to bug 2084919, perhaps firefox picked up the buggy
interface?
