Here no problem with the same version at Android 8.1.0 and 8.0.0 and Nova Launcher
Also in Android Options App and at Android Stock Launcher (Samsung und Huawei) is the right Firefox Preview Icon.

I see the same issue installing on a Nexus 6 running 7.1.1.

I can reproduce this using a Sony Xperia Z3C with Android 6.0.1. The home icon is an unnamed dark gray square. Opening the app, I see the Firefox Preview icon at the top.

Verified fixed. Using a Nexus 5 running Android 6. Though I do see some issues around the icon appearance. We are defaulting to the rounded corners icon when we should use the unboxed icon.
