Firefox SVG filter in another domain

Question

For example, my HTML file with a CSS declaration: filter: url (http://example2.com/svgfile.svg#myfilter); it contains the domain "example1.com". Does it work in Firefox? It works when the HTML file and the SVG file are in the same domain.

Answer 1

SVG resource resources must be the same with the Gecko download page. Otherwise, you can check the resulting rendering and read the cross-domain information about the resource document ...

At some point, this encoding is likely to grow CORS checking.
