Mozilla Weave, the synchronization tool for Firefox has finally launched! I am currently using it to synchronize bookmarks and preferences between my work PC and my home laptop. (I am not putting sensitive information like passwords on the Weave servers, thank you!)
Installing and using Weave is pretty straightforward if you have used Xmarks, which is what I currently use for bookmark synchronization. Download the Weave Sync addon for Firefox and install it on the computers where you need synchronization. In addition to a Weave login and password, you will also be asked to create a passphrase, that is used to encrypt your content stored on the Weave servers. If Weave works out well for a couple of weeks, I will be saying goodbye to Xmarks.
PS: I know Google Chrome has bookmark synchronization that stores the information in the user's Google Docs account. As of now, I am sticking to Firefox as I see no killer feature in Chrome that is worth the switch.
