Microsoft Internet Explorer’s market share has been on the decline for the last few years, but it has gained a bit more market share in the last month according to research from Net Applications. When Internet Explorer is measured by Net Applications, it includes all of the versions. IE gained a full percentage point in the past month and it is now sitting at 53.83%, which is the highest level since September 2011. Firefox and Chrome each dropped less than a percentage point to 20.55 and 18.57%, respectively. Note: Net Applications recently tweaked their method for measuring browser usage, but it is unclear whether this would shift favor for IE.
