CSS3d renderer blurry text on firefox

Hi, I’m new to the three.js tech so I apologize if I’m asking stupid questions. I’m working with CSS3drenderer and I have a problem when rendering my scene on Firefox. The text is a little blurry on Firefox (on chrome it’s okay). I heard that I need to change the scene scale because Firefox and chrome don’t use the same rendering tech. But when i do it as obvious my objects are far away but then what do i need to do? I would like to keep the same width, heights, positions and css style of my objects. I’ve dropped an example below (my object positions are x=0, y=0 and z=2500 and camera z=3000).

chrome result

firefox result
(It’s way more blurry in real life)

Thank you very much in advance!

Please give a jsfiddle or something like that, people will help.
