The original files were downloaded from the store and have been working until I installed NTLite 2024.4.9910.Where did you download the packages?
Store version of Firefox (ProductID 9NZVDKPMR9RD):
Code:<Identity Name="Mozilla.Firefox" Publisher="CN=082E9164-EE6C-4EC8-B62C-441FAE7BEFA1" Version="125.0.2.0" ProcessorArchitecture="x64" />
HTTP /pub release:
Code:<Identity Name="Mozilla.MozillaFirefox" Publisher="CN=Mozilla Corporation, OU=Firefox Engineering Operations, O=Mozilla Corporation, L=Mountain View, S=California, C=US" Version="125.0.2.0" ProcessorArchitecture="x64" />
I don't think the two are interchangeable MSIX files. You're supposed to integrate the Store (UWP) app.
