Java is a special programming language without whose support Mozilla Firefox on a computer will not be able to display the interactive contents of the page. Each user can easily check if he is supported by a Java browser or not.
Go to http://www.java.com/ru/download/uninstallapplet.jsp, click on the red button and wait a while. If you see the interactive content of the page, then Java is supported and all is well. If in front of you instead of the contents only a gray screen, then something is wrong. It is possible that Java is not supported or the current version is outdated.
The user can turn on Java on his own. Click on the corresponding button on the page. Mozilla will ask: temporarily allow or allow and remember? In the first case, Java turns on once. When you go back to the page, you will have to turn on Java support again. In the second case, everything is simpler. You turn on once and when you visit again, enjoy the contents.
