I think I found the solution compatible with FF31!!!
Here are two options that are well explained at this link:

I used option 1: Rodrigo-Ludgero posted this fix on Github, including an online demo. I tested this demo on Firefox 31.0 and it appears to be working correctly. Tested on Chrome and IE as well. Here is the html code:

    
    
    
    
    
    
        

            
                Custom Select
                Custom Select
                Custom Select
            
        
    

and the css:

.custom-select {
    background-color: #fff;
    border: 1px solid #ccc;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    margin: 0 0 2em;
    padding: 0;
    position: relative;
    width: 100%;
    z-index: 1;
}

.custom-select:hover {
    border-color: #999;
}

.custom-select:before {
    color: #333;
    display: block;
    font-family: 'FontAwesome';
    font-size: 1em;
    height: 100%;
    line-height: 2.5em;
    padding: 0 0.625em;
    position: absolute;
    top: 0;
    right: 0;
    text-align: center;
    width: 1em;
    z-index: -1;
}

.custom-select select {
    background-color: transparent;
    border: 0 none;
    box-shadow: none;
    color: #333;
    display: block;
    font-size: 100%;
    line-height: normal;
    margin: 0;
    padding: .5em;
    width: 100%;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
}

.custom-select select::-ms-expand {
    display: none; /* to ie 10 */
}

.custom-select select:focus {
    outline: none;
}
/* little trick for custom select elements in mozilla firefox  17/06/2014 @rodrigoludgero */
:-moz-any(.custom-select):before {
    background-color: #fff; /* this is necessary for overcome the caret default browser */
    pointer-events: none; 
    z-index: 1; /* this is necessary for overcome the pseudo element */
}
