If you're using mozilla, update to mozilla 1.4 (http://www.mozilla.org
) and then go here (http://www.pikeus.freeserve.co.uk/ju...ava-linux.html

If you're using another browser just search with google like this "<name of browser>"+"java" or replace java with "java plugin"
That should get you the information that you want
