I doubt it is something a mere browser can fix. This is going to require a change in the HTTPS standards. This occurs because of the way the Encryption is designed in the standard. . . which all browsers have to meet to work on the Internet when using HTTPS.
Well, Google could adopt the way Microsoft accesses HTTPS websites with Edge and Internet Explorer 11.0—that only requires a relatively minor code change.
This is not a hack of HTTPS. It’s merely a way to snoop URLs by redirecting HTTPS traffic through a compromised Web Proxy server. Home users and most organizations are unaffected because WPAD is rarely used in the modern era of fast WANs and near unlimited local storage.
In fact the most common use of web proxies today is to let organizations snoop their employees web acitivity - exactly what this so called ‘hack’ does.
