FirefoxDriver

Firefox Driver

Firefox driver is included in the selenium-server-stanalone.jar available in the downloads. The driver comes in the form of an xpi (firefox extension) which is added to the firefox profile when you start a new instance of FirefoxDriver.

Pros

• Runs in a real browser and supports Javascript
• Faster than the InternetExplorerDriver

Cons

• Slower than the HtmlUnitDriver

Important System Properties

The following system properties (read using System.getProperty() and set using System.setProperty() in Java code or the "-DpropertyName=value" command line flag) are used by the FirefoxDriver:

Property	What it means
webdriver.accept.untrusted.certs	?
webdriver.assume.untrusted.issuer	?
webdriver.development	Never use in production Indicates that we're in development mode.
webdriver.enable.native.events	?
webdriver.firefox.bin	The location of the binary used to control firefox.
webdriver.firefox.port	?
webdriver.firefox.profile	The name of the profile to use when starting firefox. This defaults to webdriver creating an anonymous profile
webdriver.firefox.useExisting	Never use in production Use a running instance of firefox if one is present
webdriver.log.file	Log file to dump javascript console logging to
webdriver.firefox.logfile	Log file to dump firefox stdout/stderr to
webdriver.reap_profile	Should be "true" if temporary files and profiles should not be deleted

Normally the Firefox binary is assumed to be in the default location for your particular operating system:

OS	Expected Location of Firefox
Linux	firefox (found using "which")
Mac	/Applications/Firefox.app/Contents/MacOS/firefox-bin
Windows	%PROGRAMFILES%\Mozilla Firefox\firefox.exe

By default, the Firefox driver creates an anonymous profile

Running with firebug

Download the firebug xpi file from mozilla and start the profile as follows:

   File file = new File("firebug-1.8.1.xpi");
   FirefoxProfile firefoxProfile = new FirefoxProfile();
   firefoxProfile.addExtension(file);
   firefoxProfile.setPreference("extensions.firebug.currentVersion", "1.8.1"); // Avoid startup screen

   WebDriver driver = new FirefoxDriver(firefoxProfile);
