Mozilla Firefox: Forbidden page

[Marvin Gerardo Aguero Salazar <maguero@racsa.co.cr>]

Hi folks,

Does any one of you know why there are pages I cannot visit with Mozilla
Firefox version 0.9, I get the following message:

Forbidden, this page
(http://ndiswrapper.sourceforge.net/wiki/index.php/List) is categorized
as: Shareware/Freeware.

Most, if not all, the pages with http://<xxx>.sourceforge.net are
forbidden. I have no idea as why this is happening.

Any input is welcomed.

TIA,

-Marvin
