in browser/components/feeds/FeedWriter.js there is a call to getSimpleCodebasePrincipal that needs to be converted to createCodebasePrincipal with a global context user id. it is in the init function that sets up the principal for the feed. since we're not isolating on user context id, we need the global context to be used here. > 1085 this._feedPrincipal = secman.getSimpleCodebasePrincipal(this._feedURI);

getSimpleCodebasePrincipal creates an origin attributes with the default user context ID so we don't need to fix this.
