Hi Keith. This is probably a normal behavior that's induced by the way pages are done. Can you provide a link to a page where this happens? For example, wikipedia articles often have links that lead to sections of the article and not to actually different pages, as you may know. If you click the Back button, Firefox will lead you to the section of the page you were looking at when you clicked that link. Is this perhaps what you're talking about? AJAX pages (i.e. pages that take advantage of heavy duty javascript code and server side technologies) often have troubles like these. It's very hard to prevent this from happening from the browsers' point of view, but Mozilla is trying to find a way for Firefox 4 (at least like time I checked they were). So using the back and forth buttons in gmail will probably be troublesome.
