I asked chatGPT what Wayland is since the article contains no explanation

In this context, “Wayland” refers to a protocol and a display server protocol used in Linux operating systems. It’s an alternative to the more established X Window System (X11). The article highlights that Firefox version 121.0 has integrated support for Wayland by default, indicating that the browser can now utilize Wayland’s capabilities directly on modern Linux desktops without relying on XWayland compatibility layer, thereby enhancing performance and compatibility with the native display server protocol.
