See the topic below for context. @simon found that it is caused by a span tag with the filename. The link was created with markdown.

The issue is that the linked image is a WebP file which is currently [only supported in Chrome](http://caniuse.com/#feat=webp).

Here’s the link to the related bugzilla issue: [https://bugzilla.mozilla.org/show\_bug.cgi?id=856375](https://bugzilla.mozilla.org/show_bug.cgi?id=856375).
