Microsoft's Internet Explorer (IE) and Edge browsers tumbled last month in user share as the once-universal programs ran on just one in every six personal computers worldwide.
According to U.S. analytics vendor Net Applications, the user share of IE and Edge - an estimate of the world's personal computer owners who ran that browser - plummeted by 3.3 percentage points to end November at 16.3%. The decline was the largest ever for Microsoft's browsers.
Mozilla's Firefox also stumbled badly last month, losing nearly 2 of its hard-won percentage points, slipping to 11.4%, its lowest user share since October 2016.
These numbers, and more importantly the fact that IE+Edge's and Firefox's numbers sank to such a degree, is striking. But it was as much a data reset by Net Applications as proof of massive user desertions.
