at least resolving the systemd topic, both remaining in

Code:

/tmp

and in

Code:

/var/tmp

I set it as a cronjob to be done at midnigt to remove them. So leaving it up to the user, if he wants to switch more times. By the way, opening them, they are empty. So may someone explain an empty file with such a fantastic hash-sum name.

For BSD I added at the end of

Code:

/etc/rc.shutdown

the lines of chrome and FF to be deleted.
