I like the moon in the background and I like that it is stylistically similar to the Firefox icon. My only complaint is the eye, not really a fan of the swoosh effect on the eye.

I would be more interested into a theme design for librewolf i’ve only found one so far.

For the icon I personally like the minimalistic clean design of the LibreWolf icon which speaks for the clean & optimized browser you get when you install it.

Most look very similar to the logo of kde amarok. Well, all wolf’s heads in a circle, looking to the right, will.
