Work is nearing completion on the Weave extension for Firefox. Mozilla has released the first beta version of a tool that allows you to upload your browser bookmarks, settings, history, open the card and password, and then synchronize them in a different browser instances (for example, installed on different computers). Weave also works with the Fennec browser, and has become an integral part of Firefox 4 which will be more or less a year. You can decide who wants to submit data synchronization and whether resources are to be joined or replaced.
