Maybe another outlook is that firefox has been captured, put in a box and fed just enough to keep it alive.
on mobile the complaint says:
"The six “core” apps are Google Play, Chrome, Google’s search app, Gmail, Maps, and YouTube. Manufacturers must preinstall the core apps in a manner that prevents the consumer from deleting them, regardless of whether the consumer wants them. These preinstallation agreements cover almost all Android devices sold in the United States."
So chrome must be installed, prominently, and is not able to be deleted by the device manufacturers.
In absence of this, would device manufacturers install firefox and send them some support?
