Judging by https://github.com/microsoft/winget-pkgs/blob/master/manifests/m/Mozilla/Firefox/147.0.4/Mozilla.Firefox.installer.yaml, only the .exe installers are currently in the manifest, although .msi Firefox InstallerUrl-s also exist for x64 and x86.
In the example above, these would be:
Reasons to potentially add it
If any Winget users try updating Firefox but end up with "Installer type does not match" errors, adding these installers alongside the existing .exe ones would at least on paper fix such errors.
Adding secondary installer types would be a huge gamechanger if microsoft/winget-cli#6028 was to get accepted one day, though it seems to be TBD.
Potential obstacles
None that I am currently aware of.
Sidenotes
I myself have changed from the EXE versions of Firefox to the MSIX ones on my devices, so I personally do not have all that much to gain from it. Many other users out there probably do, however.
On top of having both MSI and EXE installers, I've also found official portable versions for Beta and for Developer Edition, but those are a topic for a different occasion.
