Download files in firefox browser using selenium WebDriver

There are situations where we need to

• Download files from browser,
• Save in a specified folder on hard disk.

We will use browser preferences to [much simpler way]

• Disable file save dialog
• set download path

Download the latest geckodriver for firefox from https://github.com/mozilla/geckodriver/releases

We will use FirefoxOptions to set browser preferences

Code implementation

ublic class FileDownloadFireFox {

	public static void main(String[] args) {
		System.setProperty("webdriver.gecko.driver", "/Users/uname/sel/geckodriver");
		String downloadFilepath = "/Users/uname/sel/";
		
		FirefoxOptions options = new FirefoxOptions();
		options.setAcceptInsecureCerts(true);
		
		options.addPreference("browser.download.folderList", 2);
		options.addPreference("browser.helperApps.alwaysAsk.force", false);
		options.addPreference("browser.download.dir", downloadFilepath); 
		options.addPreference("browser.download.defaultFolder",downloadFilepath); 
		options.addPreference("browser.download.manager.showWhenStarting", false);
		options.addPreference("browser.helperApps.neverAsk.saveToDisk","multipart/x-zip,application/zip,application/x-zip-compressed,application/x-compressed,application/msword,application/csv,text/csv,image/png ,image/jpeg, application/pdf, text/html,text/plain,  application/excel, application/vnd.ms-excel, application/x-excel, application/x-msexcel, application/octet-stream");
		
		FirefoxDriver driver = new FirefoxDriver(options);
		driver.get("http://www.seleniumhq.org/download/");
        driver.findElement(By.linkText("32 bit Windows IE")).click();    
	}

}

File will be downloaded under specified location, the path specified in above code is for Mac OS, if you are using windows OS, the use

System.setProperty("webdriver.gecko.driver","C:\\Users\\uname\\sel\\geckodriver.exe");
String downloadFilepath = "C:\\Users\\uname\\sel";

For older versions of selenium < 3.10 , follow here

We will be using FirefoxProfile class to set certain preferences and download file from mozilla browser to our local hard disk.

Refer setPreferences for firefoxProfile.

Code implementation –

public class DownloadFile_FireFox {

	public static void main(String[] args) {
	      FirefoxProfile profile= new FirefoxProfile();
	     
              //Accept SSL certificate errors
	      profile.setAcceptUntrustedCertificates(true);
	      profile.setAssumeUntrustedCertificateIssuer(true);
		 
	      //Download a file in FF browser
	      profile.setPreference("browser.download.folderList", 2);
	      profile.setPreference("browser.helperApps.alwaysAsk.force", false);
		  
	      profile.setPreference("browser.download.dir", "C:\\Downloads"); 
	      profile.setPreference("browser.download.defaultFolder","C:\\Downloads"); 
	      profile.setPreference("browser.download.manager.showWhenStarting", false);
	      //Set MIME types
	      profile.setPreference("browser.helperApps.neverAsk.saveToDisk","multipart/x-zip,application/zip,application/x-zip-compressed,application/x-compressed,application/msword,application/csv,text/csv,image/png ,image/jpeg, application/pdf, text/html,text/plain,  application/excel, application/vnd.ms-excel, application/x-excel, application/x-msexcel, application/octet-stream" );
		  
	      FirefoxDriver driver =  new FirefoxDriver(profile);
              driver.get("http://the-internet.herokuapp.com/download");
              Thread.Sleep(2000);
	      driver.findElement(By.linkText("some-file.txt")).click();
     }
}
