Dear chess friends,

on many webpages of my site, where you can study chess games and play against chess engines, a Java applet is used, which has served us for many years trouble-free. In the recent years however most modern browsers like MS Edge, Google Chrome, Opera have disposed the Java applets because of the "supposedly" untrustworthy safety, which is in my opinion unreasonably. Actually, without this pages my site is now half as valuable.

Here is a workaround for this issue.

If you don’t see any Java applets (a green chess board with chess games) at the bottom of my pages, please install Mozilla Firefox until Version 51!!.

(IMPORTANT!) Beginning with Mozilla Firefox Version 52 Java applets won’t be supported by Firefox. That’s why you have to install an older version of Firefox (until Version 51) to get full access to my website. Also you must (IMPORTANT!) deactivate automatic updates of Firefox. The automatic updates can be deactivated here: Tools/Options/Advanced/Update (about:preferences#advanced). Then Firefox will never be updated and you will always be able to see the Java applets on my website.

After you go to the website http://releases.mozilla.org/pub/firefox/releases/, find the version of Firefox that you want to install (e.g. 50.0.1/). Follow the link and you should come to a new page.
If your operating system is Windows, choose the link win32/. Now you reach a new page, where you can choose between all languages, including English.
After choosing "en-US/" you will come to another page.
Click on the file "Firefox Setup 50.0.1.exe" (42M) and download Firefox on your computer.
This is the file you need to install Firefox. The installation should be done offline, without internet connection.
If you already had Firefox on your computer (e.g. Version 52), it’s necessary to uninstall it "correctly", otherwise it won’t work. With "correctly" I mean Control Panel / Add or Remove Programs.
If you weren’t user of Firefox before, you can immediately start the installation.
After that you can open Firefox offline and forever forbid automatic updates. Then you can reconnect.

Then download and install the latest version of Java or an older one.

In the Java Control Panel, which you can find in different places, depending on your operating system, (in Windows 8.1/10 you can find it via pressing the start button in the taskbar) add the site http://www.grinis.de/ (don’t forget the slash in the end), to the Exception Site List. You can find here how to do that. To configure the Exception Site List you should go to the tab "Safety". The List is shown in that tab. To add or delete any website, press "Edit Site List".

Now you have to enable Java in Mozilla Firefox. Here is the description, how to do it.

Now please open Firefox and the website http://www.grinis.de. After that go for instance to Steinitz’s 475 chess games. If Firefox wants you to confirm, whether it shall run "supposedly untrustworthy" applications on my website, please confirm pressing "Yes", and you will see a green chess board at the bottom of the page.

As there’s a big amount of operating systems and browsers, please tell me, if you should have any issues or if the java applet can even be started on other browsers. Maybe on older browsers like Internet Explorer or Netscape Java will work even better.

Meanwhile, I gradually try to create alternative pages where you can watch chess games without Java. Though there are only about 400 games.
