Currently, the WinGet package Mozilla.Firefox.de is not available in octoja. If you switch to the main Mozilla.Firefox package, the software will be installed in English, since installer-specific parameters (such as --locale de-DE or language overrides) are not currently applied when distributing via the kiosk package.
Request:
Integration of language-specific WinGet IDs (such as
Mozilla.Firefox.de) into the octoja software catalogThe ability to reliably pass the
--locale argumentor user-defined installer arguments to the client for WinGet packages. (There is already a request for this: https://feedback.octoja.de/p/installationsparameter-fur-pakete-unterstutzen)
