An X-window is just like a canvas, a rectangular space where an
application can draw to. The xserver manages this canvas and (through
the help of the window manager) decides where the window should appear
on the screen. The xserver also tells the applications when to draw into
the canvas (in case the window contents were lost and need to be redrawn).
If you open a webpage in Firefox, FF loads the webpage and starts
drawing (rendering) into the canvas. That's it.
