Selenium Firefox modifyheaders

January 4th, 2015 No comments

A few of my tests require access to modify the HTTP Request headers. Unfortunately, Selenium hides access to them to allow for portability, and to better emulate what “users” generally can change. To work around this a Firefox extension can be used and configured at runtime for this purpose.

NOTE: for Maven, you need to place a copy of the .xpi file referenced into the /src/test/resources folder for Selenium to locate it.

In the example below, I’m setting the HTTP Header for “DNT” to “1”.

public FirefoxDriver createFirefoxDriver() throws URISyntaxException, IOException {
// Specify the install location (if not default)
System.setProperty("webdriver.firefox.bin","C:\\path\\to\\Firefox.exe");
// Prevent Console log "noise" from the Selenium Firefox plugin
System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.SimpleLog");
System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", "OFF");
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.commons.httpclient", "OFF");

final FirefoxProfile profile = new FirefoxProfile();
final URL url = this.getClass().getResource("/modify_headers-0.7.1.1-fx.xpi");
final File modifyHeaders = modifyHeaders = new File(url.toURI());

profile.setEnableNativeEvents(false);
profile.addExtension(modifyHeaders);

profile.setPreference("modifyheaders.headers.count", 1);
profile.setPreference("modifyheaders.headers.action0", "Add");
profile.setPreference("modifyheaders.headers.name0", "DNT");
profile.setPreference("modifyheaders.headers.value0", "1");
profile.setPreference("modifyheaders.headers.enabled0", true);
profile.setPreference("modifyheaders.config.active", true);
profile.setPreference("modifyheaders.config.alwaysOn", true);

final DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setBrowserName("firefox");
capabilities.setPlatform(org.openqa.selenium.Platform.ANY);
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
return new FirefoxDriver(capabilities);
}

Masquerading browser User-Agent strings

October 31st, 2011 No comments

As it’s Halloween, it’s only relevant that I share a method of covering your browsers identity.

  • For MSIE, you must modify the registry. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent]
  • For Chrome (on Windows, and I assume other OS’s), you can use a startup parameter.
    C:\Users\{USERID}\AppData\Local\Google\Chrome\Application\chrome.exe --user-agent="Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_7_0; en-us) AppleWebKit/533.21.1 (KHTML, like Gecko) Version/5.0.5 Safari/533.21.1"
  • For Firefox and other Mozilla based browsers, you can mofiy the configuration in (user.js) or use a variety of add-on extensions, such as:

Interested in knowing your current User-Agent, just visit one of the following:

Many robots and spiders that are used by search engines also identify themselves by their User-Agent, if you see this activity in your logs you can often learn more about it at:
