Once you have downloaded the 'Super Fast Internet' extension and enabled it, you will notice a significant reduction in the number of adverts displayed.
As a rule of thumb, in most cases you will stop seeing advertisements altogether. Only selected websites will still manage to show you some ads. For example, if you often visit free movie streaming or torrent sites, you will probably come across one or two ads. We assure you that this is nothing compared to the countless ads and pop-ups that spam your computer unless you have an ad blocker installed.
