Probably, and I have found myself in the same situation btw, the best solution would be a fork of one of the browsers, that would (for example) only browse to addresses in the user's hosts file. That way, it could still piggyback all of the web interface machinery of a modern browser, but the things like "omg that's a self signed certificate you will die now" warnings can be safely removed, since the browser will only be able/willing to go to addresses in the user's hosts file. Just a thought.
