It _does_ work unless you hit some bug (and there have been some that affect some people). If you were an early adopter in particular there were some database corruption issues. If that's the case deleting the places database is often the best fix (especially if there's nothing in there you care about -- you're clearing private data, right?). Instructions at http://support.mozilla.com/ for this and other common problems.
The other issue is that the url bar shows both history and bookmarks. Obviously people don't want to clear their bookmarks so some data still shows up even after clearing history. This issue has been addressed in Firefox 3.5 with an option to not show bookmarks in the URL bar (on the Privacy tab in Options).
