NIS Blocked Google Images?

I recently just reinstalled my PC with Windows 7 Ultimate 64 bit and I use Mozilla Firefox with latest update (39.0). After I installed Norton Internet Security, every time I use Firefox to search image with Google, it will show only 20 of the first thumbnail images. The rest of the images won't show up. But strangely, I have no problem if using Google Chrome to search the same category image (it will show all the thumbnail images as usual). I decided to uninstall my NIS and it works fine for Firefox, but after I reinstalled the NIS, the problem occur (again), so I presume it's the NIS that blocked thumbnail images from Google?
