If the bookmark button is not visible, click the expand tap on the left side of the of the function list. This is very useful for your home computer or a computer used in a classroom. It is not useful to save bookmarks in the CSUB labs since Netscape is reloaded each time the computer is started and all saved bookmarks are lost. You can however, use the bookmarks listed on the browser in CSUB labs. Release the mouse button and Netscape will seek out and load the web page you selected.
Proxys allow only pages acceptable to the proxy list to be accessed.
You may need to reboot your computer befor the proxy takes effect. How about a book about the web and browsers. Amazon provides reviews and on-line ordering. I also suggest checking out your local book store and find which books fit your needs.
