When a JavaScript URL (javascript:) is evaluated and the result is a
string, this string is parsed to create an HTML document, which is then
presented. Previously, this document’s URL (as reported by the
document.location property, for example) was the originating javascript:
URL which could lead to spoofing attacks; it is now correctly the URL of
the originating document. This vulnerability affects Firefox < 74.
