JSON

URLs using “javascript:” have the protocol removed when pasted into the
addressbar to protect users from cross-site scripting (XSS) attacks, but if
a tab character is embedded in the “javascript:” URL the protocol is not
removed and the script will execute. This could allow users to be socially
engineered to run an XSS attack against themselves. This vulnerability
affects Firefox < 59.
