vmware player demo 12, ubuntu 15.10 32-bit, updated vivaldi this week: i cannot find the 'delete cookies' option in settings under privacy like i can on the windows version. is that just because the linux demo is behind windows demo development?
Tools/clear private data/ select what it is you want to clear or control.
Also under tools/settings/privacy, at the very bottom, there is a list of cookies you can clear one at a time. You can even filter them by domain.
