Window Background Image

In addition to editing the color schemes of the user interface, you can make the browser even more personal by adding an image to the Tab bar.
To enable and edit this option go to Settings > Appearance > Window Background Image and check the box for Show Window Background Image.
You can also select whether the image is scaled to fit or repeated. The latter is a good option for seamless patterns.
In addition, you can decide whether the image is blended together with the Window Accent Color or not.
