For an "ultra security mode" that would work, but it would break a large portion of the Web's sites (as you noted, and it's easy-ish to circumvent) :/

Conceptually I like the idea of an ultra security mode for certain use cases, but ultimately it ends up making the whole web look like a bunch of plain text emails -- no JS, probably no images (unless the are somehow sandboxed and displayed from a safe local store), links are fully visible, etc.
