Oct 29, 2018  On Mac OS X go to your Applications/Utilities folder and choose 'Terminal'. Enter the path to the application, then a space, followed by the command-line argument. For example, to start the Firefox with the Profile Manager on Mac OS X, you would enter the following. In eclipse if you explicitly set Firefox as your external browser then it will attempt to start a new instance. However, if you set Firefox as your default system browser and select that option in eclipse, it will open a new window within the existing instance. If for some reason you must have 2 instances then you can create a new firefox.

Note to Windows users! With this release you must have the Microsoft Visual Studio redistributable runtime installed on your system for the binary to run. This is a known bug with this particular release that we intend to release a fix for soon.

Added

Applications Firefox App Contents Macos Firefox Version

• Added support for HTTP HEAD requests to the HTTPD

  geckodriver now responds correctly to HTTP HEAD requests,
  which can be used for probing whether it supports a particular API.

  Thanks to Bastien Orivel for this patch.

• Added support for searching for Nightly’s default path on macOS

  If the location of the Firefox binary is not given, geckodriver
  will from now also look for the location of Firefox Nightly in
  the default locations. The ordered list of search paths on macOS
  is as follows:

  1. /Applications/Firefox.app/Contents/MacOS/firefox-bin
  2. $HOME/Applications/Firefox.app/Contents/MacOS/firefox-bin
  3. /Applications/Firefox Nightly.app/Contents/MacOS/firefox-bin
  4. $HOME/Applications/Firefox Nightly.app/Contents/MacOS/firefox-bin

  Thanks to Kriti Singh for this patch.

• Support for application bundle paths on macOS

  It is now possible to pass an application bundle path, such as
  /Applications/Firefox.app as argument to the binary field in
  moz:firefoxOptions. This will be automatically resolved to
  the absolute path of the binary when Firefox is started.

  Thanks to Nupur Baghel for this patch.

• macOS and Windows builds are signed

  With this release of geckodriver, executables for macOS and Windows
  are signed using the same certificate key as Firefox. This should
  help in cases where geckodriver previously got misidentified as
  a virus by antivirus software.

Removed

• Dropped support for legacy Selenium web element references

  The legacy way of serialising web elements, using {'ELEMENT': <UUID>},
  has been removed in this release. This may break older Selenium
  clients and clients which are otherwise not compatible with the
  WebDriver standard.

  Thanks to Shivam Singhal for this patch.

• Removed --webdriver-port command-line option

  --webdriver-port <PORT> was an undocumented alias for --port,
  initially used for backwards compatibility with clients
  prior to Selenium 3.0.0.

Changed

• Refactored Marionette serialisation

  Much of geckodriver’s internal plumbing for serialising WebDriver
  requests to Marionette messages has been refactored to decrease
  the amount of manual lifting.

  This work should have no visible side-effects for users.

  Thanks to Nupur Baghel for working on this throughout her
  Outreachy internship at Mozilla.

• Improved error messages for incorrect command-line usage

Failed To Connect To Binary Firefoxbinary(/applications/firefox.app/contents/macos/firefox-bin)

Fixed

/applications/firefox.app/contents/macos/firefox

• Errors related to incorrect command-line usage no longer hidden

  By mistake, earlier versions of geckodriver failed to print incorrect
  flag use. With this release problems are again written to stderr.

• Search system path for Firefox binary on BSDs

  geckodriver would previously only search the system path for the
  firefox binary on Linux. Now it supports different BSD flavours
  as well.
