I have no clue why this app is 3 stars on firefox, i just moved from chrome to firefox and the reviews here are innaccurate, this is by far the best free vpn on the market, no limit, if i get lucky and get the right server im able to get gigabit speeds. At the risk of sounding like a paid review (which i'd love to be) if you are looking for a free vpn these guys have nailed it.
