I don't believe there is a tool that is an "add-on" for Microsoft Edge but what you could do is use a VPN service to do the same thing. One I would recommend is Private Tunnel. Not only will it change the IP of your browser but it will also change the IP of all applications on your computer when you run Private Tunnel.
Private Tunnel is a new approach to true Internet security creating a
Virtual Private Tunnel (VPT) or Virtual Private Network(VPN) that
encrypts, privatizes, and protects your Internet traffic.
Edit (@Bobrovsky wants a free VPN service)
If your looking for a free VPN service, I would check out CyberGhost.
