This article describes how you can use the same bookmarks, passwords, and settings, across multiple computers. The mechanisms referenced here allow you to share the same user information across multiple computers without maintaining multiple copies of your bookmarks, passwords, and settings.
Firefox has no standard mechanism for sharing user information across multiple machines. In addition, there may be third-party Firefox extensions that can help you. Go to addons.mozilla.org to search for and install extensions for Firefox.
