[Package Issue]: Mozilla.Firefox: Consolidate locales into main manifest

Please confirm these before moving forward

• I have searched for my issue and not found a work-in-progress/duplicate/resolved issue.
• I have not been informed if the issue is resolved in a preview version of the winget client.

Category of the issue

Installation issue.

Brief description of your issue

As opposed to maintaining several manifests

e.g. Mozilla.Firefox.en-US,Mozilla.Firefox.en-GB, Mozilla.Firefox.en-CA

Multiple locales can be consolidated into the primary Mozilla.Firefox using the InstallerLocale tag in the installer manifest.

Likewise, locales can be consolidated for the different releases (i.e. Mozilla.Firefox.DeveloperEdition and Mozilla.Firefox.ESR

Steps to reproduce

List the multiple unncecessary packages of Firefox

winget search Mozilla.Firefox

Actual behavior

Installing Mozilla.Firefox installs the en-US version. For other locales, the user needs to specify a specific subpackage (e.g. Mozilla.Firefox.en-CA)

Expected behavior

The manifest should offer all locales, so that

winget install -e --source winget --id Mozilla.Firefox

should install according to their Windows locale (e.g. en-CA for English (Canadian))

No response

Start by inspecting the Mozilla.Firefox, Mozilla.Firefox.en-US, Mozilla.Firefox.en-GB, and Mozilla.Firefox.en-CA manifests, along with the DeveloperEdition and ESR variants mentioned in the issue. Use winget search Mozilla.Firefox to compare the current packages; done means the primary manifests include the supported locales and installation selects the locale matching Windows settings.
