selenium throws error if an instance of firefox is already open

I am using the following code to search google and click on first search result.
from selenium import webdriver
import urllib.parse
import time
from selenium.webdriver.firefox.options import Options
options = Options()
options.set_preference("dom.popup_maximum", 100)
options.add_argument("-profile")
options.add_argument("/home/blueray/.mozilla/firefox/5ertyoox.default-release")
options.page_load_strategy = 'eager'
# options.add_extension('fhnegjjodccfaliddboelcleikbmapik.crx')
browser = webdriver.Firefox(options=options)
with open("google-search-terms.adoc") as fin:
for line_no, line in enumerate(fin):
line = line.strip()
query = urllib.parse.urlencode({'q': line + " site:amazon.com"})
browser.execute_script(f"window.open('https://www.google.com/search?{query}');")
time.sleep(5)
for x in range(1, len(browser.window_handles)):
browser.switch_to.window(browser.window_handles[x])
try:
elm = browser.find_elements_by_xpath(
'/html/body/div[7]/div/div[9]/div[1]/div/div[2]/div[2]/div/div/div[1]/div/div/div[1]/a/h3')
if not elm:
elm = browser.find_elements_by_xpath(
'/html/body/div[7]/div/div[9]/div[1]/div/div[2]/div[2]/div/div/div[1]/div/div/div/div[1]/a/h3')
elm[0].click()
except Exception as e:
print("Error", str(e))
However, if one instance of firefox is open and I run the script it gives the message:
Firefox is already running, but is not responding. To use Firefox, you
must first close the existing Firefox process, restart your device, or
use a different profile.
And the program is terminated with the following error:
Traceback (most recent call last):

What should i do so that there is no error even if an instance of firefox is already open?

I'm having the same issue but only if the open firefox instance has the same profile that I'm loading in the script. If you remove the profile from this script it should run. It should also work if your code uses a different profile that the current open window is using.
You can also use the deprecated selenium 3 way of loading a profile and this avoids the error for me.
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
ffOptions = Options()
ffProfile = FirefoxProfile(r'C:\Users\Tyler\AppData\Roaming\Mozilla\Firefox\Profiles\0753x1pz.default')
ffOptions.profile = ffProfile
driver = webdriver.Firefox(options=ffOptions)
driver.get("http://www.google.com")
I'm still looking for a viable solution using the selenium 4 way of setting a profile.

Sometime, Selenium scripts are leaving web drivers open, not closing them properly.
A good pratice would be a good try/except/finally block:
driver = webdriver.Firefox()
try:
# Your code
except Exception as e:
# Log or print error
finally:
driver.close()
driver.quit()
Also, you should trying to kill any firefox processes running on your system as part of a python script, using something like this:
.....
.....
import os
os.system("taskkill /im geckodriver.exe /f")
os.system("taskkill /im firefox.exe /f")

Selenium The browser appears to have exited before we could connect

I tried to make a bot which looks up if the Bob Marley TShirt from Ajax Amsterdamn is available.
https://www.adidas.ch/de/ajax-3-jsy/GT9559.html <- there is the link
I was able to get it running (also added an telegram bot to report the succses:
#!/usr/bin/python3
from selenium import webdriver
import requests
token="" # expunged for obvious reasons
chat="" # expunged for obvious reasons
message="Available"
fireFoxOptions = webdriver.FirefoxOptions()
fireFoxOptions.set_headless()
browser = webdriver.Firefox(firefox_options=fireFoxOptions)
browser.get("https://www.adidas.ch/de/ajax-3-jsy/GT9559.html")
if ("Dieses Produkt ist leider ausverkauft." not in browser.page_source):
send_text = 'https://api.telegram.org/bot' + token + '/sendMessage?chat_id=' + chat + '&parse_mode=Markdown&text=' + message
response = requests.get(send_text)
print(response.json())
browser.close()
Working on:
selenium 3.141.0
python 3
Firefox 91.0.2
geckodriver 0.29.1
OS: Manjaro Linux
So after that I tried to deploy it on my Debian 10 Server but here is where the struggle began. I had to install Firefox 78.14.0esr and according to the github release page of the Geckodriver version 0.27.0 of it. Selenium stayed the same with 3.141.0. From what I know and what I researched the versions should be alright but when executed throw this nervewrecking error:
Traceback (most recent call last):

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities
I searched the error up and apparently you have to define the binary paths and the capability "marionette" now I did this and now the code looks like this (including some debugging stuff):
#!/usr/bin/python3
from selenium import webdriver
import requests
from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
#token="1995953311:AAH-D7S-MISkCa0yQxUc84Gf978fz0vtoqY"
#chat="1917512203"
message="just a test"
options = FirefoxOptions()
options.add_argument("--headless")
cap = DesiredCapabilities().FIREFOX
cap["marionette"] = False
binary = "/usr/bin/firefox"
options.binary = binary
browser = webdriver.Firefox(options=options, capabilities=cap, executable_path="/usr/local/bin/geckodriver")
browser.get("https://www.adidas.ch/de/ajax-3-jsy/GT9559.html")
if ("Dieses Produkt ist leider ausverkauft." not in browser.page_source):
send_text = 'https://api.telegram.org/bot' + token + '/sendMessage?chat_id=' + chat + '&parse_mode=Markdown&text=' + message
response = requests.get(send_text)
print(response.json())
else:
print("succ")
browser.close()
But now I get the following error:
Traceback (most recent call last):
File "./ajax.py", line 18, in <module>
browser = webdriver.Firefox(options=options, capabilities=cap, executable_path="/usr/local/bin/geckodriver")

self.binary, timeout)

self.binary.launch_browser(self.profile, timeout=timeout)

self._wait_until_connectable(timeout=timeout)
File "/home/webadmin/.local/lib/python3.7/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 104, in _wait_until_connectable
"The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.
Also changing the cap["marionette"] = False to True just gives me the older error message.
Thank You!

I just reverted all the changes, made an Docker container and put that on the server.

Python, Selenium "'bool' object is not callable" Error

I'm trying to prepare a bot for a platform with using python and selenium. My codes are below. When I runned I saw a error like that:

How can I fix that?
What I'm trying to do is there is a Google Captcha confirmation on login page. If there isn't don't wait much. If there is, wait until recaptcha solver plugin fix it.
If I remove "## waiting for captcha confirmation" section and add time.sleep(110) it will solved. But I need to make that similar with human. I'm waiting for your helps.
Instead of
WebDriverWait(driver,30).until(recaptchaSolved.is_displayed())
I tried that
WebDriverWait(driver,30).until(EC.visibility_of_element_located((By.XPATH, "//*[contains(text(),'Solved')]")))
But it gave an error again. Like that:

This most probably happens when you run Chrome as an administrator. Try running it "not as an admin" and check once.
Just got to Chrome's properties->compatibility and change that

Selenium python website login

I was trying over the past few hours , without success , to make webdriver.Firefox() run properly. I reinstalled geckodriver and verified it was added to the path , i tried to use FirefoxBinary but it didn't help.
I could not find any solution , and I am not sure how to fix this , I would appreciate your help.
This is the code :
#!/usr/bin/env python
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
import time
browser = webdriver.Firefox()
browser.get("https://testweb.com")
time.sleep(10)
username = browser.find_element_by_id("extpatid")
password = browser.find_element_by_id("extpatpw")
username.send_keys("username")
password.send_keys("password")
login_attempt = browser.find_element_by_xpath("//*[#type='submit']")
login_attempt.submit()
Below are the exceptions received when I tried to execute the script :

I'm not sure why you have this line:
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
but it's completely unnecessary and likely related to your ultimate problem - a wrong version of the Firefox webdriver module.
Try Chrome and see how it reacts with that.
