It's because the page or pages, you are trying to view have either flash or shockwave content on them and you do not have the macromedia flash / shockwave plug ins to see the pages.
Either download it as it suggests, or don't try to view pages that have any content apart from straight html.
If you take the second course you will have a poor experience with about 1/4 of the internet denied to you
Most computer sites nowadays have gone the multimedia route, with flash, shockwave and other visual/audio content. Without the appropriate plug in you are unable to see the info on the site.
Unfortunately too many sites are completely made in flash
Edited: as an example I tried to find some info about my printer on the epson site today and it is only available with macromedia schockwave
