Internet Explorer now has 67.55 percent of global browser market share, a drop of more than 7 percentage points in a year, according to figures from Web metrics company Net Applications released Monday. Mozilla's Firefox browser, meanwhile, has gained market share in the same time frame, climbing more than 3 percentage points to 21.53 percent.
