Make it possible to choose Geckodriver for Firefox

[soulgalore]

Meta -

OS: OS X
Selenium Version: v3.0.0-beta-2
Browser: Firefox 48
Javascript/NodeJS version

In the current version the Geckodriver is found searching the PATH. I would love to see the same implementation as for Chrome and Chromedriver where you can specify the Chromedriver using the ServiceBuilder. Or a simpler solution for now where you can specify the path to Geckodriver using a property.

That would make it easier for us to automatically choose which Geckodriver to use, so the user doesn't need to be involved (in an embedded app).

+1 with this feature.

On Node I managed to get around this by manipulating the path on process.env.PATH += ':' + pathToGeckoDriver and it seems to work on OS X and linux, but it feels pretty unstable and hacky.

But on Windows sadly it is not working even after including geckodriver path in Environment variables and the FF48 is not at all getting opened.

File "appscraping.py", line 37, in appopen
driver = webdriver.Firefox(capabilities=caps)
File "C:\Python27\lib\site-packages\selenium-3.0.0.b2-py2.7.egg\selenium\webdriver\firefox\webdriver.py", line 65, in init
self.service.start()
File "C:\Python27\lib\site-packages\selenium-3.0.0.b2-py2.7.egg\selenium\webdriver\common\service.py", line 71, in start
os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

Is there a way of using the Firefox ServiceBuilder when creating a driver via a Builder? For Chrome I use setDefaultService, but there's no equivalent for Firefox.

There is a somewhat detailed description of the underlying problem and grunt based solution here:
