JSON

A website could have obscured the fullscreen notification by using a URL
with a scheme handled by an external program, such as a mailto URL. This
could have led to user confusion and possible spoofing attacks. This
vulnerability affects Firefox < 115, Firefox ESR < 102.13, and Thunderbird
< 102.13.
