Hi everyone,<p>This is a very small add-on I've developed as a proof-of-concept to synchronize video playbacks in almost every website with another browser with P2P connections, without needing a server. With this extension you can watch videos online with your friends without explicitly needing to tell each other the duration or actions.<p>It's all free and open-source, so feel free to check it out and leave a comment :)<p>Source code: <a href="https://github.com/kaangiray26/sync-everything">https://github.com/kaangiray26/sync-everything</a>
