It would be great of Mozilla could save the relative positions of its windows and the URLs they were displaying. With the features Mozilla currently has (saving locations, saving the current contents of forms, etc.), it should be possible to save all the "state" information on a user's Mozilla browser windows before closing so they can be restored on open. This could either be through the OS calls to restore state (like Gnome on Linux, or Explorer does on Windows) or a "save workspace/restore workspace" option in the menus.
