Firefox versions prior to 121
Description
The issue is related to the absence of a warning when a user attempts to navigate to a new protocol handler under certain conditions. This could potentially allow a remote attacker to impact data integrity.
Recommendations
For versions prior to 121, update to a version 121 or later to resolve the issue. As a temporary workaround, consider restricting access to new protocol handlers until a patch is available.
