i just downloaded selenium and wanted to try just simple
code:
from selenium import webdriver
driver = webdriver.Firefox(executable_path='/usr/local/bin/geckodriver')
driver.get("https://www.youtube.com")
error:

it also doesn't work if i change
driver = webdriver.Firefox(executable_path='/usr/local/bin/geckodriver')
to
driver = webdriver.Firefox()
i made gecko driver executable with chmod +x geckodriver
moved it to usr/local/bin
and set path like that:
export PATH=$PATH:/usr/local/bin/geckodriver
still doesn't work
with webdriver-manager the error is

Appearently, the issue occurs due to non-administrative privileges. The location where you have your driver at needs root privileges to be executed/run. I suggest you moving your driver to somewhere in your home directory where you don't need root privileges to launch the driver.
You can always install the Firefox driver on the fly. Just make sure you have the normal version of firefox installed. This doesn't have any kind of dependency on your local setup.
All you need to do is:
self.driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
from
from webdriver_manager.firefox import GeckoDriverManager

I have the following script that makes use of selenium for authentication process.
I'm on Ubuntu 20.04 LTS, the computer was reformatted in the past few days, the same script worked before, from reading other threads I suspect that this has to do something with the root user/privileges.
I've tried both Firefox (geckodriver) and Chrome (chromedriver), here's what I did:
Chrome:
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
import chromedriver_autoinstaller
chromedriver_path = chromedriver_autoinstaller.install()
browser = Chrome(executable_path=chromedriver_path)
The error:

I've made sure that my chrome is installed in the default folder, tried to use options such as --no-sandbox, tried to set binary location to where chrome is, did not work.
I've installed chrome in its default path on Linux.
I've tried with the --no sandbox option
I've tried specified the binary path by setting `options.binary_path = '/path/to/google-chrome'
I've installed Xvfb on my machine
I've tried downloading the chromedriver and geckodriver manually and adding them to the path (after placing in /usr/local/...)
I've tried this python script to open a url in portable Firefox on windows, but I get SessionNotCreatedException traceback.

exec_path = "path\\to\\geckodriver32.exe"

browser.get('some_url')
Here's the traceback:

I am using:
windows 7 (64 bit)
python 3.7
selenium 3.141
geckdriver v0.24.0 (64 bit)
FirefoxPortable 68.0.1 (64 bit)
Any idea how to get the portable Firefox working?
Change the path to Firefox binary to the firefox.exe file inside "App" folder.
E.g. 'path\\to\\FirefoxPortable\\App\\Firefox\\firefox.exe'
I'm try to run the selenium python package in Debian 9 Stretch for web-scraping purposes; I installed such versions for the following softwares:
Python 2.7.13 (with Pycharm 2018.2 Community Edition)
Mozilla Firefox Quantum 61.0.1 (64 bit)
Selenium 3.14 (with GeckoDriver v0.21.0)
When I try to call the web driver by running:
driver = webdriver.Firefox(executable_path="/home/quant/Documenti/Executable/geckodriver")
I get the following error message in the python console:
Traceback (most recent call last): File "", line 1, in

What's wrong?
The path of the executable is correct and the file is executable; moreover, by adding the firefox_binary option to the webdriver.Firefox function
as follows:
driver = webdriver.Firefox(firefox_binary="/snap/bin/firefox", executable_path="/home/quant/Documenti/Executable/geckodriver")
one gets the same error shown above.
Any help or suggestion will be appreciated.
Thanks all.

I have tried EVERY thread I can find and no solutions are working. I'm not sure if this is because it is a python 3.6 problem?
Did you try giving the chrome webdriver path directly inside the parenthesis?
Same code works perfectly on my windows machine.
I have set environment variables, else i need to provide the path directly.
I am using geckodriver for Firefox and I'm running Python 3 with Selenium. This is my code in the file script.py:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://www.google.com')
Once I run it with python3 script.py with my terminal, it launches Firefox but simply doesn't load the page, nor does it insert the link in the address bar. My geckodriver is installed at this location: /usr/local/bin/geckodriver.
After waiting for about a minute, I get the following error:
Traceback (most recent call last):

I already searched a lot for fixes but none of them worked.
After I realized, I was using Firefox ESR instead of the normal one, I switched to the normal Firefox version and faced this problem:
Traceback (most recent call last):
File "script.py", line 3, in <module>

selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service /root/Downloads/firefox-56.0.1/firefox/firefox
Which version of Selenium/Geckodriver/Browser are you using?
Anyway, do you set the executable_path:
driver = webdriver.Firefox(executable_path=r'pathTo/geckodriver')
?
EDIT
If you are using:
Selenium version = 3.6.0
Geckodriver version = 0.19.0
Firefox version = 52.4.0
Your problem is Firefox. From GeckoDriver releases, is recommended Firefox 55.0 (and greater).
