Not a Kubuntu issue as also seen here on Ubuntu immediately after running the snap version of Firefox for the first time. The directory doesn't seem to reappear after being deleted no matter how many more times Firefox is restarted. Moving issue to the Firefox package.
As the Thunderbird snap creates a thunderbird.tmp directory in ~/Downloads the first time it is run I'll add a thunderbird task.
