I have seen advice (from an earlier post) stating that simply running separate instances of chrome will not help, and that it is necessary to create separate windows users, one of which (user A) has a clean (no extensions) installation of chrome which can then be used for banking/other sensitive applications. An extended version of chrome run by another user (user B) would then be unable to view user A's browser content. Is this correct?
Further, is it safe for user A (but not user B) to be an administrator account?
