I made a theme on Firefox Colour and the image that I put under the 'custom backgrounds' tab isn't appearing as the background. Instead it uses the Background Colour from the Custom Colours menu. How would I fix it, so that the image is displayed behind the tabs? (My settings are in the images below.)

I am not familiar with the extension. Have you looked at the "official documentation"?
