ajax post call doesn't work in Firefox and IE, Chrome works

Question

so i have this problem, i have a Java Back-End which is basically restful services + db layer, which answers queries from the Javascript front end.

I have a javascript ajax request that works perfectly in Chrome, but doesn't even get to the server when i use Firefox/IE.

AJAX ERROR is : readyState=0, status=0, statusText="error"

Here is the web.xml

ajax javascript call

$(document).on('click', '.btn-login', function (event) {
    event.preventDefault();
    var holdUserName = document.getElementById("username1").value;
    var holdPass = document.getElementById("password1").value;
    Cookies.set('username', holdUserName, {expires: 1});
    console.log(Cookies.get('username'));
    console.log(holdUserName);
    console.log(holdPass);
    var logIn =
            {
                "username": holdUserName,
                "hash": holdPass
            };
    $.ajax({
        type: 'POST',
        async: false,
        cache: false,
        url: 'http://www.localhost:8080/library/login',
        contentType: "application/json",
        data: JSON.stringify(logIn),
        success: function (data, textStatus, xhr) {
            console.log(xhr.status);
            if (xhr.status == 200) {
                $(location).attr('href', 'runScript.html')
            }
        },
        error: function (error, xhr, ajaxOptions) {
            console.log(error);
            console.log(ajaxOptions);
            console.log(xhr.status);
            console.log(xhr.statusText);
        }
    })
});

rest service

@POST
@Path("login")
@Consumes({MediaType.APPLICATION_JSON})
public Response login(@HeaderParam("authorization") String auth, User usr){
    System.out.println(usr.getUsername());
    System.out.println(usr.getHash());
    Object ok = false;
    try {
        ok = (new LoginHandler(usr.getUsername(),usr.getHash()).call());
    } catch (Exception e) {
        e.printStackTrace();
    }
    if(ok.equals(true)){
        return Response.status(200).build();
    }else{
        return Response.status(403).build();
    }
}

When i try to make a request to the restful webservice with Postman, i get the response, and everything is ok, Chrome works too, but Firefox and IE are giving me a headache? Any help?

Much thanks!
