java - Using Selenium WebDriver with Tor

Question

Because Tor Browser Bundle is just a patched version of Firefox, it seems that it should be possible to use a FirefoxDriver with Tor Browser. This is what I've tried so far:

String torPath = "C:\Users\My User\Desktop\Tor Browser\Start Tor Browser.exe";
String profilePath = "C:\Users\My User\Desktop\Tor Browser\Data\Browser\profile.default";
FirefoxProfile profile = new FirefoxProfile(new File(profilePath));
FirefoxBinary binary = new FirefoxBinary(new File(torPath));
FirefoxDriver driver = new FirefoxDriver(binary, profile);
driver.get("http://www.google.com");

This results in a blank Tor Browser page opening with a popup message: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I know that the profile is valid/compatible because I can successfully start the browser and profile with:

binary.startProfile(profile, profilePath, ""));

I don't know how to send commands to a browser opened in such a manner, however.

I've found similar questions, but I'm specifically looking for a Java solution, preferably tested on Windows.

I'm using a standalone Selenium library that can be downloaded here and the Tor Browser Bundle that can be downloaded here.

Because Tor Browser Bundle wasn't letting me use the WebDriver extension, I found a workaround in which I ran Tor from a regular Firefox browser. With this method, as long as the Tor Browser is open, you can use Tor with a regular Firefox browser.

• Open Tor Browser:

  File torProfileDir = new File(
          "...\Tor Browser\Data\Browser\profile.default");
  FirefoxBinary binary = new FirefoxBinary(new File(
          "...\Tor Browser\Start Tor Browser.exe"));
  FirefoxProfile torProfile = new FirefoxProfile(torProfileDir);
  torProfile.setPreference("webdriver.load.strategy", "unstable");
  
  try {
      binary.startProfile(torProfile, torProfileDir, "");
  } catch (IOException e) {
      e.printStackTrace();
  }
  

• Open Firefox with some configurations:

  FirefoxProfile profile = new FirefoxProfile();
  profile.setPreference("network.proxy.type", 1);
  profile.setPreference("network.proxy.socks", "127.0.0.1");
  profile.setPreference("network.proxy.socks_port", 9150);
  FirefoxDriver = new FirefoxDriver(profile);
  

• Close browsers. Note that if you plan on doing a lot of closing and reopening (useful in obtaining a new IP address), I advise setting the profile preference toolkit.startup.max_resumed_crashes to a high value like 9999.

  private void killFirefox() {
      Runtime rt = Runtime.getRuntime();
  
      try {
          rt.exec("taskkill /F /IM firefox.exe");
          while (processIsRunning("firefox.exe")) {
              Thread.sleep(100);
          }
      } catch (Exception e) {
          e.printStackTrace();
      }
  }
  
  private boolean processIsRunning(String process) {
      boolean processIsRunning = false;
      String line;
      try {
          Process proc = Runtime.getRuntime().exec("wmic.exe");
          BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
          OutputStreamWriter oStream = new OutputStreamWriter(proc.getOutputStream());
          oStream.write("process where name='" + process + "'");
          oStream.flush();
          oStream.close();
          while ((line = input.readLine()) != null) {
              if (line.toLowerCase().contains("caption")) {
                  processIsRunning = true;
                  break;
              }
          }
          input.close();
      } catch (IOException e) {
          e.printStackTrace();
      }
      return processIsRunning;
  }
