Ihave exactly the same problem with FF notified by Rohan,
the computer, same architecture. It did happened after upgrading to Ubuntu jaunty 9.04
LANG=es_ES.UTF-8
Gnome 2.26.1
Kernel 2.6.28-12-generic
Nvidia GeForce 6200

If I click the right button of the mouse on the back button of the navigation bar, a small pop list appears with the last pages visited related with the actual page. Otherwise the left-click on the backbutton does not work.
Bookmarks are not saved, I lost all the bookmarks, a pity.
