The Power Of Open Source

More than 800 developers along with thousands of testers, designers, writers, and a global community of contributors make the Mozilla Application Framework the best in the world. This award-winning engine has been applauded for its safety, performance, and customizability. Flock not only utilizes, but also passionately contributes to and supports the technology that Mozilla has created to power the Firefox browser.

Mozilla Heritage

Flock and Mozilla share both source code and a mission to preserve choice and innovation on the Internet. In 1994 Netscape introduced a web browser that ushered in a new era of the Internet as a mass medium. The Mozilla Project traces its roots to Netscape where the open source project was formed in February 1998. Exactly one decade later, Netscape was discontinued. From the DNA of the original web browser, two exceptional, world-class web browsers have been created: Firefox and Flock. And Netscape has recommended each as the best new browser alternatives available anywhere.

Flock’s Relationship with Mozilla

Flock is proud to be a part of the Mozilla ecosystem, and we give back 100% of what we change or fix in the core. Flock has not 'forked' the Firefox code base, nor will we. When the Flock development team finds a bug or an opportunity to tune the reliability or performance of the core Firefox engine, we fix it - and then we push it upstream to the Firefox team so it can get rolled into the Mozilla Application Framework.

Flock’s unique and innovative technology builds upon the best of Mozilla’s foundational Firefox platform to provide an unparalleled social browsing experience.
