If Firefox 3.x cannot be supported at this time, Symantec ought to at least provide an option in preferences so that users can choose which of their browser(s) they wish to apply Norton Confidential to. It is very annoying to constantly get the message that Norton Confidential does not support Firefox 3.0. I use both Firefox and Safari, and want the protection in Safari (where it works) so I do not wish to completely turn it off. Also, the error message does not exactly explain the problem. It states that Norton Confidential only works with Firefox versions 1.5 and later. Firefox 3.0 is a later version!
