Firefox blocks Java for the NYTimes chess player; I do not get a message allowing me to use any of the options described in the Java article for allowing it.
The lead sentence gives the essential issue. When I try to use the NYTimes chess player (to review games posted on the NYTimes website) I get a message that my security settings have blocked it. The player uses Java, and it's trying to open when I get the message, so I assume that Java is the problem. The article on how to enable Java describes several messages that might appear that would give me the option to allow it to run, but none of those messages appears in this circumstance--Firefox simply refuses to permit Java to run. Nothing in my security settings appears to relate to this issue.

Hi if you go to Tools》add on you can click the plug in tab and manually enable java here. Please be aware of the security risks before enabling it. In the about:config page you can also search for the Java plug in entry.
Note that you can get a possibly colored Lego icon on the left end of the location bar that indicates that Firefox is blocking a plugin.
I checked the add-on manager; Java Deployment Toolkit 7.0.510.13 10.51.2.13 (two separate numbers, but shown on the same line) is set to Ask to Activate, along with a warning to use it with care. However, when I click for More Information I am told that it is blocked without any suggestion for how to unblock it. Java Platform SE 7 U51 10.51.2.13 is set for Always Activate, and there is no prompt for More Information. I recently installed the most recent version of Java; this was when the absolute inablility to use it began (this applies to the NYTimes Chess Player, the Acrostics program, and possibly others; I can still do the Sudoku, although with a warning when I first use it at a particular session). I have checked the articles mention in cor-el's response, but their application to my problem is not clear. On question, however--are the Java versions showing in my add-on manager the most recent ones that I just downloaded? If not, how do I get add-on manager to recognize the most recent versions (which, according to Java, are the only versions on my computer). Thanks for your help.

You can add it to the Java Console exception list as well if you have not tried that already.
