GED not working in FireFox 35

I have the website jmorland.com and I ‘m using Google Doc Embedder 2.5.18 with WordPress 4.1 and FireFox 35. I receive a redirect 404 message when I try to access [gview file=”https://jmorland.com/wp-content/uploads/2015/01/Elondon_1.pdf”%5D

I can directly access https://jmorland.com/wpcontent/uploads/2015/01/Elondon_1.pdf on FireFox.

The link to my page is https://jmorland.com/91-2/.

The file size is less than 2 MB and I’ve cleared the cookies and caches from FireFox.
