Mozilla Weave version .6 boosts performance, adds new features
Apart from the old Weave sync kung fu - bookmarks, history, and passwords - the newest version can now keep your Personas up to date across multiple machines. Performance has gotten another boost, and there's a new about:weave page that allows for easier management of your preferences and Weave account.
[update] The first-time sync also now includes the option to specify which direction you want to sync. That's a welcome change, since it means no more deafult Firefox bookmarks sneaking into my Weave profile in the cloud.
