Hello, and sorry for the slow reply here. Per the dpkg terminal log, there was a 'temporary failure in name resolution issue' (i.e. DNS look up issue) when the system tried to install the Firefox snap from the snap store. Given that this was likely a one-off random failure and the store is normally working fine, I'll close this as Invalid. Thanks.
