1223624 - IsURIPotentiallyTrustworthy should check nesting and wss

Status: NEW

Description

[Tanvi Vyas[:tanvi]]

IsURIPotentiallyTrustworthy should check nested protocols.  We probably should just check the innermost scheme here against https, file, etc:
http://mxr.mozilla.org/mozilla-central/source/dom/security/nsContentSecurityManager.cpp#410

We should also add wss per spec.  I'm not sure why Service Workers need an API that doesn't accept wss (https://bugzilla.mozilla.org/show_bug.cgi?id=1221365#c12)

Service workers explicitly wants only http/https.  I just landed checks in SWM to do this after the trustworthy check is made.

I raised a spec issue about this:
