2703 again

- description needs to stay changed from just cookies since it also clears site data
- keep the info about n days out of it, it's just messy (ESR users should be on version 60)
- get the values correct (I mixed them up earlier)
- fixup [setting] path
- leave in one (of two) extra [notes] I previously added
