问题
I am trying to open Firefox with selenium,i tried
from selenium import webdriver
driver=webdriver.Firefox()
But i got the following error:
selenium.common.exceptions.WebDriverException: Message: 'firefox' executable needs to be in PATH.
Selenium using Python - Geckodriver executable needs to be in PATH
I tried
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
binary = FirefoxBinary('/usr/bin/firefox')
browser = webdriver.Firefox(firefox_binary=binary)
Also tried
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.FIREFOX
caps['marionette'] = True
caps['binary'] = '/usr/bin/firefox'
d = webdriver.Firefox(capabilities=caps)
`but still did not work.
However, when i tried using the above code replacing the last line with
d=webdriver.Firefox(capabilities=caps,executable_path='/usr/bin/firefox') and having my Firefox closed from background it would open Firefox but I can't simply d.get("https://www.google.com") it gets stuck on Linux homepage and doesn't open anything.
After typing whereis firefox in terminal i got /usr/bin/firefox,also if it matters i use python 2.7
Note: I hope this isn't a duplicate of the above link because i tried the answers and it didn't fix it.
I installed geckodriver from github, and tried browser=webdriver.Firefox(executable_path="geckodriver") ,I have placed the driver is the same directory.

It is still not clear why you are seeing the error as:
selenium.common.exceptions.WebDriverException: Message: 'firefox' executable needs to be in PATH.
In majority of the cases the common PATH related error is associated with geckodriver.
However, while working with Selenium 3.x you need to download the latest GeckoDriver from mozilla/geckodriver and save it anywhere in your system and provide the absolute path of the GeckoDriver through the argument executable_path.
The following code block works perfecto to open Firefox Nightly Browser (installed at customized location):
Code Block:
from selenium import webdriver from selenium.webdriver.firefox.options import Options options = Options() options.binary_location = '/path/to/firefox' driver = webdriver.Firefox(firefox_options=options, executable_path='/path/to/geckodriver') driver.get('http://google.com/') print("Page title is: %s" %(driver.title)) driver.quit()Console Output:
Page title is: Google
