Is this about Firefox for desktop?

What hash are you talking about? Do you mean the SHAxxxSUMS to verify the installer?

Windows install hash.

Windows install hash.

Windows install hash.

I still do not understand what you mean with "install hash".

Can you describe this better with more detail /

Hi

This is install hash ex.

308046B0AF4A39CB

installs.ini:

[308046B0AF4A39CB] Default=d:\Firefox Locked=1

and profiles.ini:

[Install308046B0AF4A39CB] Default=d:\Firefox Locked=1

[Profile0] Name=Default User IsRelative=0 Path=d:\Firefox

[General] StartWithLastProfile=1 Version=2

Where does Firefox store install hash (file,registry)?

I need to write a profile creation script but I don't know where the install hash is stored?

[308046B0AF4A39CB] relates to the Windows Registry identification of the Firefox installation path.

Where?

I don't think that this hash is stored anywhere apart from profiles.ini and installs.ini, but is calculated when necessary from the installation path where Firefox was started. The installs.ini file is meant as a backup in case an older Firefox version that doesn't support dedicated profiles has rewritten profiles.ini and removed this data. The hash is used to identify a specific Firefox installation including via its full file path, so this isn't about the Firefox version, but is about the installation path (folder). The Firefox version check is done via compatibility.ini in a specific profile folder.

Do you want to write a profile creation script for something like this?

Firefox Profilemaker https://ffprofile.com/

Try it and see how it saves the created profile.
