When Firefox is installed from the Microsoft Store, the icloud_passwords_install.exe fails as it cannot find the Mozilla Firefox folder in Program Files.

The program exits with the following message:
Failed to register Firefox native messaging host manifest at C:\Program Files\Mozilla Firefox\FirefoxPwdMgrHostApp_manifest.json: open C:\Program Files\Mozilla Firefox\FirefoxPwdMgrHostApp_manifest.json: The system cannot find the path specified.

In such cases Firefox is installed in the WindowsApps folder (e.g. C:\Program Files\WindowsApps\Mozilla.Firefox_126.0.1.0_x64__n80bbvh6b1yt2\VFS\ProgramFiles\Firefox Package Root) and the installation files cannot be changed, even as administrator.

I assume the program would also fail when Firefox is not installed in its default path.

A temporary fix to this issue is to create the missing folder in Program Files so that the script can create the manifest.

Another solution would be to change the program so that it write the manifest to another location (maybe Program Data?), in order to avoid any conflicts if Firefox is not installed in its default path.
