Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 141 Description: A crafted URL utilizing a blob: URI could conceal the actual origin of the page, potentially leading to a spoofing attack. This issue specifically impacted Android operating systems. Recommendations: Update Firefox to version 141 or later.

This issue was addressed through improved state management. Visiting a malicious website may lead to user interface spoofing.

The issue is related to the notification announcing the transition to fullscreen mode in Firefox on Android. Multiple prompts and panels from both Firefox and the Android OS could be used to obscure this notification, potentially leading to spoofing of the browser UI if the user is distracted by the sudden appearance of a prompt. The notifications now use the Android Toast feature. This issue only affects Firefox on Android, with other operating systems being unaffected.
