Browser plugins

Starting with Firefox version 52, released on March 7th, 2017, Firefox will no longer be able to open the Java plugin required to use Banner. After this date, it will only be possible to use Banner through Internet Explorer. However, it is also possible to download a version of Firefox that provides extended version support. This means that we can continue using the versions of Firefox that allow the Java plugin required by Banner to work.
