Use KDE's Breeze dark and light cursors on Cookie Clicker!

Just subscribe to https://steamcommunity.com/sharedfiles/filedetails/?id=2700647149

Just add the following code to the extension:

It's browser specific so no tutorial, but this is the code you need:
Game.Loader.Replace('cursor.png',src="https://raw.githubusercontent.com/agostaxyz/cookie-clicker-breeze-cursor/main/breeze-cursorMod/cursor.png");
