Google today announced that its Analytics service will stop supporting Internet Explorer 9 next month. Starting on January 31, Google Analytics users should only use Microsoft’s browser if they are running IE10 or IE11.
Google said :
While you can continue to use IE9 after we discontinue support, some features may not work properly going forward. This update maintains our practice of supporting the newest browsers while discontinuing support for the third-oldest version, as we previously announced in September 2013.
Google warned that :
We will continue to support the latest versions of Chrome, Firefox, Internet Explorer 10 or higher, Safari and other modern browsers. Of course, you will still be able to measure visits from users of all browsers, including IE 9. We will send further reminders prior to the deprecation, but do advise you begin preparing and implementing plans for this change at your earliest convenience.
