The first developer preview release of the Flock web browser has been released to the public. Although Flock was developed on top of the Mozilla platform, the developers' approach for this program is to include a variety of services, which otherwise would only be available by visiting many websites.

According to the official FAQ however, Flock will not become bloatware, and also for the time being, it shouldn't be used as mission-critical browser, since a full security audit has not taken place yet, so this release could almost be considered a pre-beta test.
