Flock is a free web browser that makes it easy to connect with your friends and express yourself online. Flock is easy-to-use web browser heavily based upon fast and secure Mozilla Firefox and other Mozilla technologies. Upload photos, get your news, blog anything, subscribe to RSS and search your world with Flock. Flock makes it easier than ever for you to connect with your friends.
Flock was founded in 2005 on the vision that the web browser can and should enable the richest user experience possible across information-gathering, sharing, communication, self-expression and interaction. Flock's creators call it a "social browser", due to its ability to interact with popular social networking web services. Such web services include Flickr, Del.icio.us, Technorati, Photobucket, and various popular blogging and news aggregation services.
Many of Flock`s features can be attained through extensions for Firefox. For example, del.icio.us Bookmarks, developed by Yahoo!, Inc., provides integration with del.icio.us online bookmarks. Fotofox, developed as an official extension by the Mozilla Corporation, integrates with Flickr. Sage provides a built in news reader, similar to Thunderbird's.
