Hello,
i have a problem with the css rule display: flex. Well to be honest, the problem is with the Mozilla FireFox browser. Every other browser displays the page as i intend it to display, but with firefox there´s a problem.
I have a container with the class of promo that holds tree colomns with the class of coluna.

The CSS is as folows:
.conteudo .promo {
max-width: 100%;
display:flex;
flex-flow:row wrap;
justify-content:center;
}
.conteudo .promo .coluna{
-moz-box-sizing:border-box;
-o-box-sizing:border-box;
box-sizing:border-box;
width: 30.3333%;
padding: 5px;
margin: 5px;
display:flex;
flex-flow:column;
}

Is there anything i´m doing wrong because only in firefox the page isn´t displayed as it should.

I´d really need some help. Please!!!!

The page is on: www(dot)sistemagestorconteudos(dot)net/Alfaccop/Sitio8

I´ve installed the new FF Aurora and it works fine.
I have a trouble with Safari though.
It´s like a small blanket, we cover one side and it uncovers the other...
