Are you missing a bookmark feature, like e.g. creating a shortcut to your favorite site on your Desktop? Firefox's bookmark functionality can be improved / extended by installing some of the many extensions that are available for it.
One extension that I particularly recommend for those of you who have created large bookmark lists (e.g. for a research project) is Bookmark Backup from Pike. Bookmark Backup is a simple extension that helps to keep your bookmarks (and optionally other Firefox settings) safe. Each time Firefox is closed, a copy of your bookmarks file will be made to a backup location. If Firefox's bookmarks become corrupted or lost, find the most recent uncorrupted backup and copy it into your profile folder. Firefox 1.5 and up now automatically creates backup copies of your bookmarks file.
