Ending Support for IE9 in June, 2015

February 16, 2015 | 1 Minute Read

Numerous large, Web-based companies such as Google have adopted a policy that "we will only support the current and previous version of a browser" as supporting many different versions of a Web browser — particularly older Web browsers like Internet Explorer 9 — is expensive. Many of the bugs and problems we've had in tools like the Gradebook and Peer Assessment tool in the past year have been caused by the hacks put in place to support IE9. IE9 was really the last version of Microsoft's browser to not fully embrace the open standards which power the modern Web. As such, even the mighty Google has dropped official support for the browser.

Effective June 1, 2015, CoursePlus will no longer support Internet Explorer 9. You will not be locked out of signing in to CoursePlus if you use Internet Explorer 9, but an increasing number of features will not work with the browser. Technical support for IE9 will be extremely limited as well. We strongly encourage you to upgrade to IE10 or IE11, or to switch to a different browser such as Chrome if you cannot update your local copy of Internet Explorer. JHSPH IT will gladly assit you in this process should you need help.
