Hi!
Been using Facebook with Opera, but noticed that the activity stamp that this website reveals (ex. "5 mns ago") will not be hidden. This time stamp is invisible when using the FB Messenger app (with appropriate settings)m or using several desktop browsers with appropriate extensions (ex FB unseen), but I can´t figure a way to not show it (the timestamp with last activity) with Opera.
Doesn anyone know how to do it?.. Thanks!
