MFSA2021-16 Firefox: Security Vulnerabilities fixed in Firefox 88 (CVE-2021-24000)

Description
A race condition with requestPointerLock() and setTimeout() could have resulted in a user interacting with one tab when they believed they were on a separate tab. In conjunction with certain elements (such as <input type="file">) this could have led to an attack where a user was confused about the origin of the webpage and potentially disclosed information they did not intend to.
