Driven by Bart Decrem, a team of developers from California released Friday a new browser (based on Mozilla’s open source code) named Flock.

Available for Windows, Mac and Linux, the new browser is based on the latest Web technologies that attract users like the online shared database of bookmarks or built-in blog and RSS readers.

Flock is the first to integrate the possibility to read blogs in one place and not to browse for them because has a special built-in RSS reader. On the main navigation bar there is a button named “Create a blog post” to facilitate user’s blogging activity. Integration with Flickr is also available with drag-and-drop options. (Flickr is the latest Yahoo photo service). Flock easily integrates with WordPress, Six Apart and Blogger the popular blogging services.

The Flock team loves Firefox and after spending several months investigating (and writing code) how to deliver what they want to do in the form of a Firefox extension. In the end, the conclusion was that they needed to release their code in the form of a full browser. They wanted to be able to offer their users a complete end-to-end user experience, including a single browser download, an update service, technical support…. the works. Further, didn’t want to break anyone’s Firefox experience, or have their browser break, due to updates either way that have not been fully tested propagated. In the short term, that means that fewer people will use their program, but over the long term they believe it’s the right way to go. Of course there will be many people who are perfectly happy with Firefox and are not interested in trying a new browser. The good news for those folks is that there are already hundreds of Firefox extensions, many of them aimed at integrating social services into the browser.

Here are a few screenshots from Flock:

Flock is the successor to Round Two who raised money from Bessemer Venture Partners. Bart Decrem is Flock’s CEO and co-founder.
