The FirefoxProfile Constructor (String) initializes a new instance of the FirefoxProfile class using a specific profile directory.

So while using GeckoDriver and existing FirefoxProfile() instead of:

FirefoxProfile firefoxProfile = new FirefoxProfile("C:\\Users\\MinhPhuc\\AppData\\Local\\Mozilla\\Firefox\\Profiles\\tiqq1wks.dev-edition-default\\");

You need to remove the trailing slashes \\ as follows:

FirefoxProfile firefoxProfile = new FirefoxProfile("C:\\Users\\MinhPhuc\\AppData\\Local\\Mozilla\\Firefox\\Profiles\\tiqq1wks.dev-edition-default");
