1571415 - Document-Loads blocked by XCTO nosniff are not logged in the Console

Status: RESOLVED FIXED

(Core :: DOM: Security, enhancement, P1)

Description

[Sebastian Streich [:sstreich]]

Steps to reproduce:

• Load some html in an iframe with
  • MIME-TYPE /
  • XTCO-Nosniff

example on https://xtco-nosniff.glitch.me/

Firefox (if document nosniff is enabled ) will just prompt a download. Usually when we block js/css because of nosniff there is a console error indicating this. For document level loads there isn't.

That we should fix within this cycle since XCTO nosniff is prefed on by default.

Please note that we already have similar errors - maybe we can even reuse the same error, see:
