Richard, if this is the same problem being investigated here, then what would explain the icon disappearing is the firefox deb being uninstalled. You can check /var/log/apt/history.log* for info on when and why that happened. Note that this shouldn't/wouldn't have happened if you launched firefox at least once, because the launcher script from the transitional deb has some logic to rewrite the target of the favourite to point to the snap instead of the deb.
