We recently took a look at the new version of Ubiquity, a Firefox browser plugin created by Mozilla Labs that provides an interactive command-based interface for the web. Some of the features that are supported by Ubiquity could potentially be included in future versions of Firefox.

Developer Aza Raskin wrote a blog entry today that offers a first look at some design concepts that demonstrate how aspects of Ubiquity could be streamlined directly into the Firefox user interface. The natural language processing features in Ubiquity pose a significant localization challenge, he says, so it's unlikely that the full scope of Ubiquity's functionality will be included.

He aims to introduce the new features in Firefox so that they will feel native and not disrupt existing workflows. His blog entry includes mockups for several different approaches, including two that extend Firefox's AwesomeBar and one that uses a mouse-friendly sidebar interface.

Raskin also revealed the project's new mascot and icon, the Ubiquibot. The icon vaguely resembles Marvin, the depressed robot from Hitchhikers Guide to the Galaxy. The icon is still being finalized and could still see some minor changes based on user feedback.
