**Name of the Vulnerable Software and Affected Versions** Firefox for Android versions prior to 100 **Description** The issue is related to errors in saving HSTS settings in Firefox for Android. When the browser is closed or sent to the background, it would not properly record and persist these settings. This could potentially allow a remote attacker to impact data integrity. The issue only affects Firefox for Android, with other operating systems being unaffected. **Recommendations** For Firefox for Android versions prior to 100, update to version 100 or later to resolve the issue. As a temporary workaround, consider avoiding closing or sending the browser to the background to minimize the risk of HSTS setting loss.
