--- Comment #46 from antoine at thirdshelf.com ---
Michael Catanzaro: I see that SecurityOrigin.cpp has this 

// FIXME: Ensure that localhost resolves to the loopback address. 

in

bool SecurityOrigin::isLocalHostOrLoopbackIPAddress(StringView host)

I would suggest that the fix to this bug not tackle "localhost" resolution but focus on the loopback address, and a separate bug be filed for localhost.

In that context, the fix would only be changing the function MixedContentChecker::isMixedContent line 62:

return !SecurityOrigin::isSecure(url);

to

return !(SecurityOrigin::isSecure(url) || SecurityOrigin::isLoopbackIPAddress(url));

Modifications to tests would involve replacing 127.0.0.1 to localhost at the appropriate places (which would then be modified as necessary as part of a separate bug to tackle localhost rules).

Would a fix with those changes be acceptable?
