Bugzilla

I have added the following to the definition of [proxyInfo](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/proxy/ProxyInfo):

proxyAuthorizationHeader
    string. Proxy-Authorization header
       The authorization header value for the request attempt. Contains the credentials to authenticate a user agent to a proxy server.
connectionIsolationKey {{optional_inline}}
    string. An optional key used for additional isolation of this proxy connection.

Please check what I've added and let me know if there is more I should say here. As far as this issue is concerned, I realize it is the bare minimum of information but I think it covers this change. 

I'm not sure I understand how you would like to present additional information that should go in other places to describe the consequences of the change. If what I have is right, a pointer to where else this information needs to go and a rough description of what Add-on developers need to know would be greatly appreciated. If you could add the information to this issue, or send me an email with the information, I will create an issue in the documentation repo on GitHub to track the additional changes.
