Information About Browsers and Plug-ins
Since our suite of products is accessed over the Internet, it is subject to the same performance issues that affect other websites. There are some steps that schools can take to improve the performance of our products (and other websites). Britannica recommends using current versions of Internet browsers, specifically:
• Google Chrome version 52.0 or higher
• Mozilla Firefox version 45.0 or higher
• Microsoft Edge version 25.0 or higher
• Safari version 9.1 or higher
Many of our classroom and teacher resources utilize multimedia features. These require a number of standard software plug-ins included with most operating systems or Internet browsers. Britannica recommends using current versions of the required plug-ins. Current versions can be downloaded for free from the Internet. Generally, if a plug-in is missing, the browser will provide a prompt to download it. The following plug-ins are required:
• Windows Media Player version 12.0 or highest version available for the computer’s platform
• Adobe Acrobat Reader version 11.0.12 or higher
Information About Authentication and Cookies
Once a computer has been logged in, students should not be prompted to log in again.
If students are asked repeatedly to log in on the same computer, the cookies are probably being deleted. If a school provides individual network log-in accounts for each student, Britannica recommends that the school set up the network profiles so that cookies can be shared between accounts.
If school computers are set up to delete cookies periodically, then their Britannica cookie will be deleted. If possible, set up the computer so that the Britannica cookie is not deleted. Schools using Deep Freeze™, Fortres™, or other security software products that refresh computers frequently may also be deleting the Britannica cookie. Britannica recommends including the school’s Britannica cookie within the Deep Freeze™ refresh itself, so that the computer will automatically be logged in when it is refreshed.
