Mozilla is working on a new project called the "Snowl". An add-on for Firefox, Snowl aims to help you access all your messages in one place - within the browser. Currently the support is basic - only Atom, RSS feeds and Twitter are supported right now. However, we can soon expect SMS and email support later, and maybe even support for social networking sites and other sources like Gtalk, and AIM.

That makes it similar to the existing Thunderbird client, although Mozilla claims that the objective of Snowl is to "help you follow and participate in online discussions".

Users can choose to have the feeds served in two different ways. One is a typical three paned window - email style. The other option is to have it served in a "river of news" view. Messages, no matter what the source, would be searchable, irrespective of whether they are private or public.

Snowl is available for download here. But be warned, according to Mozilla, the current version is "primitive and buggy". Updates to future versions could result in loss of messages and stored data, unless you're a geek who would like to test it.

Snowl is a part of the Concept Series initiative that invites external contributions in terms of ideas and innovations for designing the development of future browsers and an enhanced web experience. For more on Concept Series, read this.
