Mozilla has released an update to Snowl, a plugin first released in August, which allows you to track RSS feeds and Twitter updates in your browser without navigating away from the web page you're currently reading.

Version 0.2 includes an updated river view that groups messages together in a single column, and a new stream view that lets you see messages in your sidebar. To be honest, the stream view looks pretty much like sidebar you get from other Twitter Firefox addons lke Twitbin, TwitKit, or TwitterFox. But most of those plugins let you see detailed information about your Twitter messages, like which ones are replies or direct messages. Snowl doesn't.

Still, as you could probably guess from the low version number, Snowl 0.2 is still a work in pogress. And it does have a few nice features, like the ability to send and receive Tweets from multiple Twitter accounts.
