Hello, and sorry for the slow reply here. The dpkg terminal log suggests that it failed to download the Firefox snap from the snap store. Was there by any chance anything unusual about your network setup, or any particular reason why your system might have failed to connect to the snap store to download the Firefox snap? Otherwise I'm afraid there's not much to go by here to try and debug this. Thanks.
