BTW, FF has a setting in Tools>Options>Content where one can disable JavaScript within the browser. See essexboy's post above.
Java and JavaScript are two different things..!!

Sorry, guys.
Some things I have yet to learn. Reason I noted javascript in the browser is because without it running, then things such as accessing webmail is not possible unless one uses an older version of it that does not require it, c|net member logon not doable without it, even mediafire will not work without it, Avast text reply box is missing the common icons for text and link enhancement, and so on. Since it is the java plugin from Oracle that is 99% of the problem, have been testing running the browser without javascript and finding it seems to be used in everything everywhere I go.
Do not have java anything installed atm, just so you know. It is apparent that FF, at least, provides their own version of java in the form of a FF javascript and one still needs that to view normal web content within the browser. Just experimenting.
