By comparing Edge's old and new shares, it was evident that as much as half of the earlier Edge traffic had been faked by bots. The portion of Edge's share credited to bots fluctuated month to month, but fell below 30% in only 4 of the 19 months for which Net Applications provided data... Microsoft's legacy browser, Internet Explorer (IE) also was revealed as a Potemkin village. Under the old data regime, which included bots, IE's user share was overblown, at times more than double the no-bots reality. Take May 2016 as an example. With bots, Net Applications pegged IE at 33.7%; without bots, IE's user share dwindled to just 14.9%. Together, IE and Edge - in other words, Microsoft's browsers - accounted for only 16.3% of the global user share last month using Net Applications' new calculations... In fact, the combined IE and Edge now face a once unthinkable fate: falling beneath Mozilla's Firefox.
StatCounter's stats on browser usage already show more people have already been using Firefox than both of Microsoft's browsers combined -- in 12 of the last 13 months.
