SVG does not display in Firefox

[sjvudp]

Following the example shown in https://lindell.me/JsBarcode/ I used code like this to create a CODE39 barcode:

<table>
  <tr><td><svg id="BC-Test"/></td></tr>
</table>
<script type="text/javascript">JsBarcode('#BC-Test', 'Test');</script>

When running the code, SVG is generated, but Firefox does not display anything: <svg id="BC-Test" width="212px" height="142px" x="0px" y="0px" viewbox="0 0 212 142" xmlns="http://www.w3.org/2000/svg"
