Are you still able to reproduce this issue? I know the Firefox snap has some inherent limitations, such as not being able to access /tmp. However, I can't think of any reason why non-snap Firefox like from the mozillateam ppa wouldn't be able to access it. Can you also please double-check to make sure that this is indeed Firefox from the mozillateam ppa and not the Firefox snap? Thanks.
