Mozilla has released an updated version of Weave, a Firefox plugin that lets you synchronize your profile, settings, and passwords across multiple computers. In other words, every time you change your bookmarks, web site login information, or other data on your work computer, the changes will be reflected on your home machine as long as you have Weave installed on both systems.

Weave 0.4 adds support for preference syncing, automatic logins, and support for Fennec 1.0 beta 2 for Maemo Linux. That last one means you the mobile version of Firefox for Nokia Internet Tablets can be configured to have all of your desktop bookmarks, passwords, and other settings with just a few clicks. Eventually Weave should also work with Fennec for Windows Mobile and other mobile platforms, which could save you an awful lot of time when setting up a mobile browser.
