Show HN: Quantum Safety Firefox browser add-on

With the building interest in adopting post quantum cryptography and using quantum safe methods over the Internet, I was seeking a way to know if my web browser session was protected. Unlike the padlock icons that show if you connected over HTTPS/QUIC/TLS, there didn't seem to be any easy way to tell if a web browser session was using post quantum cryptography. Of course you can dig through info in the developer tools, but this is a lot of hassle when doing ordinary browsing. So, I built a simple Firefox extension that shows a different icon if the main web page is protected using post quantum cryptography or not. (Unfortunately, Chromium/Chrome doesn't provide APIs to do something similar.) Please let me know what you think.
