Does anybody know where the ID: 308046B0AF4A39CB comes from?

If you use a Windows 10 1909 64 Bit and you can find this in the installs.ini and in the profiles.ini of users, if you have a Firefox ESR 64 Bit in Version 78.10.0 installed. The INI-Files looks like this:

Installs.ini: [308046B0AF4A39CB] Default=Profiles/8U9skky2.default-esr Locked=1

Profiles.ini: [Install308046B0AF4A39CB] Default=Profiles/8U9skky2.default-esr Locked=1

[Profile0] Name=default-esr IsRelative=1 Path=Profiles/8U9skky2.default-esr

[General] StartWithLastProfile=0 Version=2

This ID can vary if you have a 32 bit ESR-installation as well and the only place I could find it is in the registry

[HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\TaskBarIDs] C:\Program Files\Mozilla Firefox=308046B0AF4A39CB

But also here it differs sometimes.

I need to know where the ID comes from and if I can rely that if this ID is used, I will always address the Firefox ESR 64 Bit no matter which version.

Chosen solution

Update (solved): Just in case someone had to deal with this issue too: We have used the ID above and could successfully migrate from x86 to x64 of Firefox ESR without forcing the users to create a new profile.

We have had over 28,000 successful installations with a modified INI-File after installation and have successfully used the already existing user profile which was created with the 32 bit version of Firefox ESR.

Meanwhile we are using the 78.13 ESR-version of Firefox.

If anybody needs details on this, just drop me a note or answer here to provide you with details.

Meanwhile I have found the ID in the registry table of the MSI as well. But still have no clue what the ID 308046B0AF4A39CB means and why it is part of the INI-files. Any insight on this would be highly appreciated.
