Firefox vs Chrome App

Due to recent evil moves by Google to push Web Environment Integrity down our throats, I want to use Firefox web app instead of Chrome web app on my Android device. I noticed the Firefox installed app has a black circle as icon, but Chrome one has the right icon.

Is this a big in Voyager or some other Google/Android discrimination?

Edit: Installing Voyager from m.lemmy.world fixed the issue for now.

Thanks for all the tips.
