inb4: Sorry for the terribly oversized images that take a very long time to load, click on the links and read the question after you don't want to wait!
So, I am making this prototype site where I am making a fake 3D effect with moving 2d images with the mouse. I wanted to use a blur filter when a user clicks on one of the triangles to focus on the popup.
My problem is that it completely crashes on firefox when I add blur. I have no problem with blurring in chrome, but for some reason in firefox, the background image that needs to be centered is right-justified and cropped by its own div, and if I change the inspector to a position of the background that it leaves the buggy area,
here is a screenshot of chrome followed by what i get in firefox.

I do not quite understand what to do at this moment in order to abandon the idea of ββblurring. Any solutions ideas are appreciated.
