Nothing in this world is difficult if you simply read instructions. Here is a link for Sandboxie. Very easy to use. My Mother knows nothing about pc's except how to get online. What settings are you talking about in Firefox. I have never had to play with any settings. But I do uncheck the Bookmarks toolbar. All I ever do is install Firefox and let it rip. Then I add on Ad blocker Plus, Flash Got, Yahoo Toolbar and Febe. I also add on some themes. I like making Firefox look differnet.
