Using Selenium WebDriver with Tor

Because Tor Browser Bundle is just a patched version of Firefox, it seems that it should be possible to use a

with Tor Browser. This is what I've tried so far:

String torPath = "C:\\Users\\Christophel Family\\Desktop\\Tor Browser\\Start Tor Browser.exe";
String profilePath = "C:\\Users\\Christophel Family\\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);

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) {
  • Open Firefox with some configurations:

    FirefoxProfile profile = new FirefoxProfile();
    profile.setPreference("network.proxy.type", 1);
    profile.setPreference("network.proxy.socks", "");
    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")) {
        } catch (Exception e) {
    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 + "'");
            while ((line = input.readLine()) != null) {
                if (line.toLowerCase().contains("caption")) {
                    processIsRunning = true;
        } catch (IOException e) {
        return processIsRunning;
