I am using Orion theme for my webpage. It looks good in every browser but Firefox. The problem is that there is bxslider at the bottom of the pages, and on Firefox it appear on the top and on the right side. That doesn’t happen in the main/index page.

I’ve checked the size of the images, just in case I was using bigger images than the container, but that wasn’t the issue.
What can it be?
Please, I will really appreciate any help.
