Google Browser Sync
Posted June 27, 2006on:
Google Browser Sync for Firefox is an extension that continuously synchronizes your browser settings – including bookmarks, history, persistent cookies, and saved passwords – across your computers. It also allows you to restore open tabs and windows across different machines and browser sessions.
I have tried & found it useful but firefox takes some time to start but thats ok.
