Mozilla bug tracking the removal: https://bugzilla.mozilla.org/show_bug.cgi?id=1172165
I've thrown a comment in there that it's broken our homepage.

@daurnimator Not sure what we can do.
In any case, this makes it even more urgent to get the new onboarding process

Do we directly link the view-source?

Yes.

As reported by another user, the title has been changed to reflect a change in Chrome 53 which no longer allows linking to view-source.

Worth mentioning that view-source is also broken in IE 11 and Edge (it launches the Microsoft Store in an attempt to find an application that can handle "view-source")
