Flock is built on the Mozilla Firefox open-source browser, so it has all the features you've come to expect in a high-quality web browser, like intuitive buttons and menus, personal customizability, reliable security, enhanced privacy protections, and automated updating. However, Flock is much more than that! The Flock Social Web Browser has been fully integrated with a wide range of social networking websites and popular blogging tools. So with Flock, you can now keep in touch and share text, links, pictures, video and more with friends, family and co-workers across the entire internet with unparalleled speed and seamless ease.

Most of the features in Flock use java script :

The java script  engine in Chromium allows Flock to keep you up to date with all your friends and favorite feeds, while keeping the browser's performance top notch

Flock Sidebar:

The sidebar is the hub of activity in Flock. It keeps you informed with feed content and social streams so you don't have to leave the web page you are on. As soon as you sign into your social services and/or subscribe to RSS and ATOM feeds, the sidebar starts delivering what's new with your friends and favorite content

Channel Surf the Web:

The sidebar works like the channels on a TV. Use the "channel changer" drop down menu at the top of the sidebar to see just friends on Facebook, just friends on Twitter, all friends, just feeds, etc. But this is better than TV, because you can create any channel you want!

Share everything with Flock:

Talk about the news, the funny video you just found, or anything else you stumble upon. Just click the Talk button, write a comment, and get back to what you were doing. We'll automatically add the link, and even shorten it for you.

Browser Extensions:

We know there are lots of people who want to customize and personalize their online experience, and browser extensions can be a great way to do that. Google Chrome extensions work with Flock.

Who says you can't take it with you:

Flock provides you the option of creating a free account that stores your favorite sites and feeds, your social networking accounts, and all the groups you make for your sidebar. You can access your account from any Flock browse.
