Selenium get(url) issue on Firefox

I'm having some issue opening going to an URL with Selenium + mocha. This is the line of code I'm using.

return driver.get('http://localhost/ClickSuscribe/#/MisProductos')

I've found that there are some issues with angular urls however I haven't found a solution.

The error is Error: timeout of 40000ms exceeded. Ensure the done() callback is being called in this test.

This is the test case:

it("Is visible", function() {
        if(viable)
        {
            return driver.findElements(webdriver.By.id('activarMiSitio')).then(function(misProductos){
                misProductos[0].getAttribute("class").then(function(webElement){
                    if(webElement==='ng-hide')
                    {
                        console.log('Element not found');
                    }
                    else{
                        console.log('Element exists');
                    }
                }).then(function(){
                    driver.sleep(500);
                    //return driver.get('http://localhost/ClickSuscribe/#').catch(r => console.log(r));
                    return driver.get('http://localhost/ClickSuscribe/#/MisProductos').catch(r => console.log(r));
                });/*.then(function(){
                    driver.sleep(2000);
                    return driver.getCurrentUrl();
                }).then(function(currentUrl){
                    driver.sleep(1000);
                    console.log(currentUrl);
                });*/
            });
        }
        return console.log("No está loggeado");
    });

PS: this does work in Chrome and IE
