The only certified and supported browsers for Blackboard include Firefox 4.x (Mac and Windows), Internet Explorer 8 (Windows), and Safari 4 and 5 (Macintosh only). We typically recommend people to use Firefox with UR Blackboard because we have seen the least number of issues with that browser and often works as an alternative browser when someone has technical difficulties with IE or Safari. However, Firefox 4 is not yet certified for Blackboard so please continue using Firefox version 4.x . We will post updates as browser compatibility information is updated.
Did you upgrade and need to go back a version? Use the following links to download previous versions:
