Try using firefox 46 0 1  It best matches with Selenium 2 53  https   ftp mozilla org pub firefox releases 46 0 1 win64 en-US

If you re on OSX using Homebrew  you can install old Firefox versions via brew cask   brew tap goldcaddy77 firefox brew cask install firefox-46   or whatever version you want   After installing  you ll just need to rename your FF executable in the Applications directory to  Firefox    More info can be found at the git repo homebrew-firefox   Props to smclernon for creating the original cask

I had the same issue and found out that you need to switch drivers because  support was dropped   Instead of using the Firefox Driver  you need to use the Marionette Driver in order to run your tests   I am currently working through the setup myself and can post some suggested steps if you d like when I have a working example   Here are the steps I followed to get this working on my Java environment on Mac  worked for me in my Linux installations  Fedora  CentOS and Ubuntu  as well     Download the nightly executable from the releases page Unpack the archive Create a directory for Marionette  i e   mkdir -p  opt marionette  Move the unpacked executable file to the directory you made Update your  PATH to include the executable  also  edit your  bash profile if you want   bangbang  Make sure you chmod  x  opt marionette wires-x x x so that it is executable In your launch  make sure you use the following code below  it is what I used on Mac    Quick Note  Still not working as expected  but at least gets the browser launched now   Need to figure out why - right now it looks like I need to rewrite my tests to get it to work   Java Snippet  WebDriver browser   new MarionetteDriver    System setProperty  webdriver gecko driver     opt marionette wires-0 7 1-OSX

Unfortunately Selenium WebDriver 2 53 0 is not compatible with Firefox 47 0  The WebDriver component which handles Firefox browsers  FirefoxDriver  will be discontinued  As of version 3 0  Selenium WebDriver will need the geckodriver binary to manage Firefox browsers  More info here and here  Therefore  in order to use Firefox 47 0 as browser with Selenium WebDriver 2 53 0  you need to download the Firefox driver  which is a binary file called geckodriver as of version 0 8 0  and formerly wires  and export its absolute path to the variable webdriver gecko driver as a system property in your Java code  System setProperty  quot webdriver gecko driver quot    quot  path to geckodriver quot     Luckily  the library WebDriverManager can do this work for you  i e  download the proper Marionette binary for your machine  Linux  Mac  or Windows  and export the value of the proper system property  To use this library  you need to include this dependency into your project   lt dependency gt       lt groupId gt io github bonigarcia lt  groupId gt       lt artifactId gt webdrivermanager lt  artifactId gt       lt version gt 4 3 1 lt  version gt   lt  dependency gt       and then execute this line in your program before using WebDriver  WebDriverManager firefoxdriver   setup     A complete running example of a JUnit 4 test case using WebDriver could be as follows  public class FirefoxTest        protected WebDriver driver        BeforeClass     public static void setupClass             WebDriverManager firefoxdriver   setup                Before     public void setupTest             driver   new FirefoxDriver                After     public void teardown             if  driver    null                driver quit                          Test     public void test                Your test code here          Take into account that Marionette will be the only option for future  for WebDriver 3  and Firefox 48    but currently  version 0 9 0 at writing time  is not very stable  Take a look to the Marionette roadmap for further details  UPDATE Selenium WebDriver 2 53 1 has been released on 30th June 2016  FirefoxDriver is working again with Firefox 47 0 1 as browser

In case anyone is wondering how to use Marionette in C    FirefoxProfile profile   new FirefoxProfile       Your custom profile var service   FirefoxDriverService CreateDefaultService  DirectoryContainingTheDriver    geckodriver exe       Set the binary path if you want to launch the release version of Firefox  service FirefoxBinaryPath     C  Program Files Mozilla Firefox firefox exe   var option   new FirefoxProfileOptions profile    IsMarionette   true    var driver   new FirefoxDriver      service      option      TimeSpan FromSeconds 30      Overriding FirefoxOptions to provide the function to add additional capability and set Firefox profile because selenium v53 doesn t provide that function yet   public class FirefoxProfileOptions   FirefoxOptions       private DesiredCapabilities  capabilities       public FirefoxProfileOptions             base                  capabilities   DesiredCapabilities Firefox             capabilities SetCapability  marionette   this IsMarionette              public FirefoxProfileOptions FirefoxProfile profile            this                  capabilities SetCapability FirefoxDriver ProfileCapabilityName  profile ToBase64String                public override void AddAdditionalCapability string capabilityName  object capabilityValue                 capabilities SetCapability capabilityName  capabilityValue              public override ICapabilities ToCapabilities                 return  capabilities            Note  Launching with profile doesn t work with FF 47  it works with FF 50 Nightly   However  we tried to convert our test to use Marionette  and it s just not viable at the moment because the implementation of the driver is either not completed or buggy  I d suggest people downgrade their Firefox at this moment

I eventually installed an additional old version of Firefox  used for testing only  to resolve this  besides my regular  secure  up to date  latest Firefox installation   This requires webdriver to know where it can find the Firefox binary  which can be set through the webdriver firefox bin property   What worked for me  mac  maven   tmp ff46 as installation folder  is   mvn -Dwebdriver firefox bin  tmp ff46 Firefox app Contents MacOS firefox-bin verify   To install an old version of Firefox in a dedicated folder  create the folder  open Finder in that folder  download the Firefox dmg  and drag it to that Finder

Firefox 47 0 stopped working with Webdriver   Easiest solution is to switch to Firefox 47 0 1 and Webdriver 2 53 1  This combination again works  In fact  restoring Webdriver compatibility was the main reason behind the 47 0 1 release  according to https   www mozilla org en-US firefox 47 0 1 releasenotes

New Selenium libraries are now out  according to  https   github com SeleniumHQ selenium issues 2110  The download page http   www seleniumhq org download  seems not to be updated just yet  but by adding 1 to the minor version in the link  I could download the C  version  http   selenium-release storage googleapis com 2 53 selenium-dotnet-2 53 1 zip  It works for me with Firefox 47 0 1   As a side note  I was able build just the webdriver xpi Firefox extension from the master branch in GitHub  by running   go   javascript firefox-driver webdriver run     which gave an error message but did build the build javascript firefox-driver webdriver xpi file  which I could rename  to avoid a name clash  and successfully load with the FirefoxProfile AddExtension method  That was a reasonable workaround without having to rebuild the entire Selenium library

It seems to me that the best solution is to update to Selenium 3 0 0  download geckodriver exe and use Firefox 47 or higher   I changed Firefox initialization to    string geckoPathTest   Path Combine Environment CurrentDirectory   TestFiles  geckodriver exe     string geckoPath   Path Combine Environment CurrentDirectory   geckodriver exe     File Copy geckoPathTest  geckoPath    Environment SetEnvironmentVariable  webdriver gecko driver   geckoPath     firefoxDriver   new FirefoxDriver
