Norton Confidential stipping text from Firefox 4 - Any way to selectively turn off?

Any plain, non-HTML text on a webpage is being ignored (stripped from the page source). 

Will not allow text input to forms.

 

I see from a previous post that Firefox 4 is not supported.

 

But there should be a way to selectively disable Confidential on a per browser basis.  I use Safari and Firefox.

 

If Confidential does not (yet) work with FF4, then it should stay away from it.

 

Is it possible to keep Confidential running so as to protect the rest of the system while not messing with Firefox?
