"Weave" weaves

Since last many days I have been using add-on of firefox. Its called "Weave". It syncs the bookmarks, history, tabs etc. I have installed it on both work and home machine. The most useful for me is tab sync. I usually open lot of tabs and then hate to close it(???). With weave I can access all the open tabs on various computer. I love this thing about cloud. Can access anything from anywhere.
