Well, I use Mozilla as my browser, but I can't view some of the objects of certain site I visit. This usually happens when you visit site with Flash animation or Javascript. If "Missing Plugins" tab appear on your browser, you can also click it to let your browser installs it automatically.
Otherwise, simply click the link below to download the plugins, then install.
