Which add-in is "Java Script"?
Suddenly, this morning I get a message that Java Script is not enabled. I'm not able to access Yahoo! mail, Gmail or iCloud mail. When I search for "Java Script" I get some 300+ add-ins, the first 50 or so don't appear to be just plain Java Script. What is the exact name for a Java Script add-in which will allow me to use my mail programs?

Javascript is not an add-in, but a programming language like basic, C, java and so on. It is often used on web pages to create dynamic effects like moving figures and similar effects. Hence it is included in the html code itself. For different reasons you maybe would like to switch off the possibility to run java scripts e.g. for security reasons, and in older versions of Firefox there was an option in the settings were you could enable or disable the possibility to run such scripts. Nowadays this option is removed, but is included in the more hidden ones which you reach by writing about:config in the Location bar. If you do so, you will get a "This might void your warranty!" warning, and after clicking the I'll be careful, I promise!-button you will enter the about:config page. Search for javascript.enabled, which normally has the value true. Double-click on that line, or after selecting it press enter on the keyboard, and the value will toggle to the other value, false. However, you might have loaded an add-on which blocks the java script. I can imagine there are lots of them. One that I use is NoScript, which lets me select individually which web sites I will allow running java scripts on my computer, and which ones I will deny this. Take a look among the add-ons you have loaded, if maybe one of them can block the java script possibility.

Make sure that JavaScript is enabled and isn't blocked.
- The javascript.enabled pref should be true on the about:config page
