JSON

A “data:” URL loaded in a new tab did not inherit the Content Security
Policy (CSP) of the original page, allowing for bypasses of the policy
including the execution of JavaScript. In prior versions when “data:”
documents also inherited the context of the original page this would allow
for potential cross-site scripting (XSS) attacks. This vulnerability
affects Firefox < 57.
