What browser supports Handshake?

I'm curious to know, what web browsers are currently compatible with the Handshake protocol? Is it only available on select browsers or has it been integrated into popular browsers like Chrome, Firefox, or Safari? As someone who's interested in exploring the world of decentralized domains, I'd like to ensure that I have the right tools to access Handshake-based websites seamlessly. Can you provide a list of supported browsers or offer any insights into the compatibility of Handshake with various web browsers?
