Install Firefox on your work laptop and you’ll want to have access to the same bookmarks, preferences, standard form information and even your passwords. If you spend time browsing the same sites, you’ll want the browser to remember and store this information. Problem is that we might add a bookmark to Firefox on our desktop PC, then forget it’s not available on our laptop.
Firefox Sync is the solution. This is an official Firefox add-on from Mozilla that enables you to share your browser information across every edition of Firefox where you have Sync installed. You create an account, enter a unique username and dual-password, then on first run the information is stored on a secure remote server. Install Weave on another computer, log in, then the information is synchronised back to the new machine.
Firefox Sync will synchronise your bookmarks, stored passwords, the information you use regularly within web forms, some of your most important preferences, your browsing history and even your open tabs.
The biggest problem with using Firefox Sync is that it only synchronises your Firefox-based information. XMarks will attempt to synchronise information across your different web browsers.
Important: Firefox Sync is now built in to Firefox 4 onwards. This is included for legacy Firefox 3.x users only
Official addon from Mozilla that enables you to synchronise your Firefox information across your computers. Problem is, it only supports Firefox.
