Java works just fine in IE, but, Firefox 18.0 tells me that java is not on my system


Cannot get java to be recognized in Firefox 18.0. Have completely wiped older versions of Java from system and installed latest several times and in addons get message that firefox has blocked older version of java and when I test in firefox get message that there is no java on my system. But, when I test using IE it tells me that is there and working.

The first thing to ask yourself is do you really need Java ?

Remember use of Java now and on many previous occasions may have involved security risks. If you wish to learn more or use Java on Firefox see

Thanks for the info. You make some good points, but, that still does not explain why Java is recognized in IE, but, not in Firefox 18.0.
