Firefox assistant Home Button : Only Open Firefox Home Screen

Hello. I’ve simple question regarding Firefox replacing android assitant. I know there is widget for android to search the web, and firefox also able to replace home button.

The question is why they behave different? Why on Assistant launch, it only launch firefox and not opening the url bar? Does it intended to be like that? Isn’t it convenient for people to directly open the URL bar than only opening firefox only?

Any pointer to enable it directly open URL bar when pressing android assistant is appreciated. Thank you.
