The new Flock beta browser now runs on Webkit which is also part of Safari and Google Chrome. Flock which has about 8 million users has also landed a new feature where you can create a Flock account and sync your settings to the "cloud".
Users can use the cloud feature to take their accounts to any Flock browser without having to reset it again and again. Considering that most of the other browsers too have an option to sync profiles or at-least bookmarks, it made more sense to have it in the newest Flock beta too. Apart from that Flock almost remains the social browser people have known it to be.
The switch from Firefox code to Chromium will come as a big jolt for Mozilla whose internet browser Firefox’s popularity has been going down since the launch of Google Chrome. Also the team at Flock had initially worked with the Mozilla team on the Netscape project before moving towards creating Flock, so their decision to branch out Flock to Chromium will be even more bitter.
