Oh sorry I assume everyone uses tabbed browsing, you can do this in either ei or firefox not so sure about other browsers. If you right click on any link in the site and choose either new window or tab then you open a page in the site while keeping the old one open. That way you can have as many pages open as you wish at the same time. You can also go file, new window or tab and then open a new page to the site from there as well. Either way works. I hope that made more sense, I find I often browse several sites at once that way.
