Firefox won't display the SVG book covers properly ...

Compare the link above in Firefox and Chrome. It used to be displayed just fine in Firefox, but I think something went wrong with the latest update.
If any one know a solution to this issue it would be great.
Thanks.
If you check your browser inspector, than you will see an error:
Inside your SVG image there are many of them, looking like:
Either create less accurate SVG (less details), or create it some other way.
Since it is rendered well in webkit browsers, than maybe you can use wkhtmltoimage to convert it server side to PNG or JPG.
