I'd like to add also that most of the time when i press the back button, it attempts to redirect my browser to crappy advertising contents.
e.g http://i.imgur.com/TpxpzIw.png
(i was viewing a post on linkedin and once clicked back, it tried to redirect me into one of these shitty ads domains...luckily i had uBlock plugin enabled to prevent stupid click-jacking and unauthorized redirects, it wont happen every time but when it do is just a mess.)
