  • Internet Explorer 8 and Internet Explorer 9 are tested in Standards Mode. Some known issues can be resolved by using Compatibility Mode (emulates IE7 behavior).
  • Both Google Chrome and Mozilla Firefox have moved to a rapid release cycle. At the time of testing, Chrome 16.0 and Firefox 9.0 were the latest available versions. Since then, new stable versions may have been released and widely adopted. Blackboard is supporting all newer stable versions of Chrome and Firefox.

About Browser History and Caching

A cache is a temporary storage area where frequently accessed data can be retained for rapid loading. A web browser cache holds copies of pages that pass through it - all items you have accessed or downloaded from the Internet, including images, sounds, Web pages, and cookies. These items are stored on your computer, usually in the Temporary Internet Files folder.

Why clear your cache?
You may occasionally encounter an error message, a "Page Not Found" display, a "Momentarily Unavailable Message" etc. This could be due to a problem with the system, maintenance, or a number of other reasons. If you decide to go back to this url later, you may see this same message even though the problem is corrected because your browser has pulled the page from your cache.

How to clear your cache:

  1. In Internet Explorer:
    1. Click on the Tools menu, click Internet Options. The Internet Options box should open to the General tab.
    2. On the General tab, in the Browsing the Internet section, click the Delete button. This will delete all the files that are currently stored in your cache.
  2. In Firefox:
    1. Click on Tools, Options, then select the Advanced panel. In the Offline Storage section, click Clear Now.
  3. In Safari (Mac OS X):
    1. Click on the Safari menu, select Reset Safari. Select the items that you want to reset, then click Reset.


You can set your browser to automatically clear cache, and you can re-size your cache storage to maintain more cached files to speed up performance; this, however, increases the likelihood that you will access stale content.

How to set your browser to automatically clear cache:

Internet Explorer

  1. Click on the Tools menu, click Internet Options. The Internet Options box should open to the General tab.
