Firefox Sync. formally weave. I always wanted that I can continue my Firefox session from one place to anther. You don’t need to save password, you don’t have to save you history through Google Toolbar. You wont need bookmark addons. This is simply great. How many times did you left your computer at work on/hibernated because you thought you will loose your tabs(currently open sites). Sync currently supports continuous synchronization of your bookmarks, browsing history, saved passwords and tabs.
