Selenium - FireFox Driver Usage

Use of FireFox Profile

Available constructors

Here we will see how Firefox driver can make use of a already created profile in firefox.
To check out which profile Firefox is using currently  enter about:support in Firefox address bar and check for "Profile Folder".

To create / modify/ delete a new Firefox profile 

To create, rename, or delete a profile, you have to perform the following steps:

1. Open the Firefox profile manager. To do that, in the command prompt

terminal, you have to navigate to the install directory of Firefox; typically, it

would in Program Files if you are on Windows. Navigate to the location where

you can find the firefox.exe file, and execute the following command:

firefox.exe -p

It will open the profile manager that will look like the following screenshot:

Note that before executing the above command, you need to make sure you

close all your currently running Firefox instances.

2. Use the Create Profile... button to create another profile, Rename Profile...

button to rename an existing profile, and Delete Profile... button to delete one.

Firefox Profile :
Firefox profile has a default constructor and other constructor taken an argument of type file.

Use of constructor FirefoxDriver(FirefoxProfile profile)

      // using a already created profile  
      public static void fireFoxProfileA(WebDriver driver) {  
           FirefoxProfile profile = new FirefoxProfile(  
                     new File("C:\\Users\\sudas\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\t1skcchd.sudas1"));  
   
           driver = new FirefoxDriver(profile);  
           driver.get("http://www.yahoo.com");  
      }  
   

      // Creating an instance of firefox profile for a specific plugin and store as JSON  
      public static void fireFoxProfileB(WebDriver driver) {  
           FirefoxProfile profile = new FirefoxProfile();  
           try {  

// adding a extension to the new Firefox session
                profile.addExtension(new File("C:\\Java_Source_Code\\FireFoxExtensions\\firebug-2.0.13-fx.xpi"));  
                String json = profile.toJson();  
                // write the profile to a file  
                BufferedOutputStream bos = new BufferedOutputStream(  
                          new FileOutputStream(new File("C:\\Java_Source_Code\\FireFoxExtensions\\profile.json")));  
                bos.write(json.getBytes());  
   
                driver = new FirefoxDriver(profile);  
                driver.get("http://www.yahoo.com");  
                bos.flush();  
                bos.close();  
           } catch (IOException e) {  
                // TODO Auto-generated catch block  
                e.printStackTrace();  
           }  
      }  

Use of preference with Firefox 

FirefoxDriver overwrites all the default preferences of Firefox in the user.js file
for you

To set the preference use the Key, Value pair

Use FireFox profile with preference

Firefox profile methods

Here I am using an already existing profile and setting a preference on the profile

      // using firefox profile along with preference   
      public static void fireFoxProfileA(WebDriver driver) {  
           FirefoxProfile profile = new FirefoxProfile(  
                     new File("C:\\Users\\sudas\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\t1skcchd.sudas1"));  
           //setting preference   
           profile.setPreference("browser.startup.homepage", "https://www.yahoo.co.in/");  
           driver = new FirefoxDriver(profile);  
 //          driver.get("http://www.yahoo.com");  
      }
