vulnerabilities as referenced in the mfsa2021-20 advisory.

  - A malicious webpage could have forced a Firefox for Android user into executing attacker-controlled
    JavaScript in the context of another domain, resulting in a Universal Cross-Site Scripting
    vulnerability.Note: This issue only affected Firefox for Android. Other operating systems are
    unaffected. Further details are being temporarily withheld to allow users an opportunity to update.
    (CVE-2021-29953)

  - When Web Render components were destructed, a race condition could have caused undefined behavior, and we
    presume that with enough effort may have been exploitable to run arbitrary code. (CVE-2021-29952)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
