Browser Update Home
The following table illustrates browser user market share including the
use of current and legacy versions of the respective browser. Current includes the current version offered by the browser vendor and
may also include the most recent version, providing the version is supported
with automatic security updates from the vendor. For example, for
Internet Explorer, "current" includes both Internet Explorer 8 and Internet
Explorer 9. Legacy refers to prior versions and those that are no-longer
supported.
The following information is provided for informational purposes only
and is subject to change without notice. While the data provided is
considered representative of users worldwide, OTA recommends sites analyze
their specific usage statistics including pages viewed and time spent online
to best determine use and edge cases. Sites with highly engaged
banking and or e-commerce users may find significantly higher levels of current
browser usage than as outlined below. Based on preliminary data,
some sites are reporting use of outdated browsers to be less than 25%.
Note: The terms Current and Legacy are not intended to be used in
consumer communications, and have been provided to help quantify the number
of users with outdated and legacy browsers.
