save a copy under acroreader plugin of firefox

[Yuandan Zhang]

Hi,
I  am using firefox acroreader plugin to view pdf file. When I try to 
save a copy, I alway get a error message 'not a super user' and refused 
to save a copy of the pdf file.

How to fix it?

my Firefoox is 1.0.3 at FC3  2.6.10-1.770_FC3. The acrobat reader plugin 
is 5.0
Thanks

Yuandan
