Launching the firefox browser in Selenium in node

Here is the sample code to launch the firefox browser using Node.js

 
var webdriver = require(‘selenium-webdriver’);

var driver = new webdriver.Builder()
.forBrowser(‘firefox’)
.build();

driver.get(‘https://www.softpost.org’);
driver.close();
driver.quit();

You should have geckodriver in your PATH for firefox 47.0.1 onwards You may get below error on windows 64 if you use 64 bit Geckodriver. To fix that error, use 32 bit driver.

 
WebDriverError: Unable to parse new session response: {“error”:”unknown error”,”
    message”:”Expected browser binary location, but unable to find binary in default
    location, no ‘moz:firefoxOptions.binary’ capability provided, and no binary flag set on the command line”}
