We'll need to find out what is hung exactly. I know snapd has a bug just like this at the moment.

Also the squares you can see are bug 2056526.

[Daniel van Vugt (vanvugt)]

Since your log ends with:

Mar 10 14:11:30 corrado-n4-nn-0310 systemd[1]: run-snapd-ns-firefox.mnt.mount: Unmounting timed out. Terminating.

we'll move it to snapd.

Problem disappeared after recent updates so I think it can be considered fix released
