We only need to change pref.
Chrome already have this as default(bug 647010 comment 87) so I do not expect that we will break something.
Do we need an intent-to-ship for this?

Pushed by email@example.com: https://hg.mozilla.org/integration/mozilla-inbound/rev/1a59ea77d44f Change a pref so that an auth prompt requested by an image resource loaded from cross-originis not allowed. r=ckerschb
Posted the site compatibility note: https://www.fxsitecompat.com/en-CA/docs/2017/http-auth-dialog-can-no-longer-be-triggered-by-cross-origin-images/
I've documented this on MDN: * Added a note to the Fx59 rel notes: https://developer.mozilla.org/en-US/Firefox/Releases/59#Security * Added a small section to the HTTP authentication page: https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication#Authentication_of_cross-origin_images Let me know if this is OK. Thanks!

Thanks! Looks good. Thanks.
Hello! This bug is just the same as my Bug 647010, which I informed Mozilla about in March 2011. This is vulnerability in all browsers, which support Basic/Digest Authentication, as I wrote in my entry. So a lot of web browsers are vulnerable, not only Firefox. I called this attack as Onsite phishing (or Inline phishing). It can be used (including by phishers) for stealing of logins and passwords of users of web sites.
