macOS: Firefox PKG Installer

We're currently deploying Firefox for MacOS via the available DMG installer. I face a lot of "error messages" in Intune saying that the app can't be updated because it is currently running:
The app is running and could not be updated. The update will be tried the next time the device syncs. (0x87D30145)

With the DMG installer you don't have options for pre-install/post-install scripts, so I'm unable to "persuade" my users to do the update.

With the PKG installer you could add an pre-install osascript to close the browser (without losing open tabs) and a post-install script to start the browser again after the successful update.

They offer all versions even with language specific options on this site: https://ftp.mozilla.org/pub/firefox/releases/

Thanks for taking a look at this and considering adding the PKG installer as alternative version :)

Kind regards,
Manuel
