Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 120
Firefox ESR versions prior to 115.5.0
Thunderbird versions prior to 115.5.0
Description
The issue is related to the black fade animation when exiting fullscreen mode, which has a similar duration to the anti-clickjacking delay on permission prompts. This could be exploited to trick users into clicking on a permission grant button that appears after the animation, essentially allowing for a clickjacking attack. The vulnerability can be exploited by a remote attacker.

For Firefox ESR versions prior to 115.5.0, update to version 115.5.0 or later to resolve the issue.
