I am getting error message as

It seems that FF Binary is not readable

I tried to give all permissions to said folder, however with no luck.

I believe you don't really need to specify the path at first place if your Firefox browser is installed at the default location.

I suspect that the escape character "\" is getting void. Can you use your path as given below and try again?

C:\\\\Program Files (x86)\\\\Mozilla Firefox\\\\firefox.exe

Also, make sure that the location is valid.

So how do you solve the problem , if the install location is not default ? Im using Selenium 3 and its no possible for me to use it with Firefox Portable with a not default path.

I get same exception as the thread owner.

You can use FirefoxOptions,

FirefoxOptions options = new FirefoxOptions();
        options.setBinary("Path to your ff binary");

and you can pass it to webdriver as below.

caps.setCapability(FirefoxOptions.FIREFOX_OPTIONS, options); //caps is DesiredCapability.
        driver = new RemoteWebDriver(new URL(String.format("http://%s:4444/wd/hub", grid)), caps);

Hope that helps!

Ok i finally can start Firefox Portable but the next Problem is , its not starting to test a url

Following code

FirefoxOptions options = new FirefoxOptions();
options.setBinary(new FirefoxBinary(new File(config.getFf_path())));
options.setProfile(new FirefoxProfile(new File(config.getFf_profile())));
                       

            DesiredCapabilities capabilities = DesiredCapabilities.firefox();
            capabilities.setCapability(FirefoxOptions.FIREFOX_OPTIONS, options);
            capabilities.setCapability(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, UnexpectedAlertBehaviour.IGNORE);
            System.setProperty("webdriver.gecko.driver", config.getGeckodriver_path());
            driver = new FirefoxDriver(capabilities);
            driver.manage().window().maximize();
            driver.get(this.url);

My code never passes after the code line "driver = new FirefoxDriver(capabilities). It just starts Firefox Portabe, show me my profile directory but dont do driver.manage and no driver.get(this.url)...its just stopped. No timeout nothing.
