A website could have obscured the full screen notification by using the
file open dialog. This could have led to user confusion and possible
spoofing attacks. Note: This issue only affected macOS operating systems.
Other operating systems are unaffected. This vulnerability affects Firefox
< 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
