Good enough to satisfy security geeks, no, because no measure you take will ever be good enough. However if you want something that's good enough for most purposes then Camino has been doing something pretty close to this since it was first released (I'm not aware of any other browser that's even tried). When you're asked for credentials, the dialog rolls down out of the browser title bar in a hard-to-describe scrolling motion a bit like a supermarket till printout. In other words instead of a random popup appearing in front of you from who knows what source and asking for a password, you've got a direct visual link to the thing that the credentials are being requested for. You can obviously pepper and salt this as required (and I wouldn't dream of deploying something like this without getting UI folks to comment and test it on real users first), but doing this is a tractable UI design issue and not an intractable business-model/political/social/etc problem.
