Firefox 4 uses the same bookmarks file that Firefox 3.6 uses.

Thanks. That's encouraging. The computer in question is used by a very young boy. Presently he can start the computer, click Firefox to start, and then click his choice of visible programs (all kids programs). He is not ready to have to search out his programs. Is there a way to have them appear upon starting Firefox? I would prefer not to stick with present version nor check how other browsers handle it.
