Access to file download dialog in Firefox

Question

Is there any kind of API that can allow me to manipulate a file download dialog in Firefox? (I want to access the one that appears when user does something, not initiate one myself).

What I want to do is to access this dialog from Selenium (and whether Selenium "privileged mode" is enough to access chrome interface is something I am not sure about as well).

Answer 1

I have a solution for this issue, check the code:

FirefoxProfile firefoxProfile = new FirefoxProfile();

firefoxProfile.setPreference("browser.download.folderList",2);
firefoxProfile.setPreference("browser.download.manager.showWhenStarting",false);
firefoxProfile.setPreference("browser.download.dir","c:\\downloads");
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk","text/csv");

WebDriver driver = new FirefoxDriver(firefoxProfile);//new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

driver.navigate().to("http://www.myfile.com/hey.csv");

Answer 2

I was stuck with the same problem, but I found a solution. I did it the same way as this blog did.

Of course this was Java, I've translated it to Python:

fp = webdriver.FirefoxProfile()

fp.set_preference("browser.download.folderList",2)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir",getcwd())
fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/csv")

browser = webdriver.Firefox(firefox_profile=fp)

In my example it was a CSV file. But when you need more, there are stored in the ~/.mozilla/$USER_PROFILE/mimeTypes.rdf

Not that I know of. But you can configure Firefox to automatically start the download and save the file in a specific place. Your test could then check that the file actually arrived.

Answer 4

Web Applications generate 3 different types of pop-ups; namely,

 1| JavaScript PopUps
 2| Browser PopUps
 3| Native OS PopUps [e.g., Windows Popup like Upload/Download]

In General, the JavaScript pop-ups are generated by the web application code. Selenium provides an API to handle these JavaScript pop-ups, such as Alert.

Eventually, the simplest way to ignore Browser pop-up and download files is done by making use of Browser profiles; There are couple of ways to do this:

• Manually involve changes on browser properties (or)
• Customize browser properties using profile setPreference

Method1

Before you start working with pop-ups on Browser profiles, make sure that the Download options are set default to Save File.

(Open Firefox) Tools > Options > Applications

Method2

Make use of the below snippet and do edits whenever necessary.

FirefoxProfile profile = new FirefoxProfile();

String path = "C:\\Test\\";
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", path);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/msword, application/csv, application/ris, text/csv, image/png, application/pdf, text/html, text/plain, application/zip, application/x-zip, application/x-zip-compressed, application/download, application/octet-stream");
profile.setPreference("browser.download.manager.showWhenStarting", false);
profile.setPreference("browser.download.manager.focusWhenStarting", false);  
profile.setPreference("browser.download.useDownloadDir", true);
profile.setPreference("browser.helperApps.alwaysAsk.force", false);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.download.manager.closeWhenDone", true);
profile.setPreference("browser.download.manager.showAlertOnComplete", false);
profile.setPreference("browser.download.manager.useWindow", false);
profile.setPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);
profile.setPreference("pdfjs.disabled", true);
       
driver = new FirefoxDriver(profile);
