How to start Firefox with with specific profile Selenium Python geckodriver

问题

Here is my code:

profile = webdriver.FirefoxProfile('C:\\Users\\Administrator\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\kvycjolb.Prdel')
driver = webdriver.Firefox(profile)

Im not getting any error and firefox starts, but it just does not load with this profile: I have tried changing / to // etc.. but no luck.

This also does not work:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
binary = FirefoxBinary("C:\\Program Files\\Mozilla Firefox\\firefox.exe")
profile = FirefoxProfile("C:\\Users\\Administrator\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\kvycjolb.Prdel")
driver = webdriver.Firefox(firefox_profile=profile, firefox_binary=binary, executable_path="C:\\aprog\\geckodriver.exe")
driver.get('https://google.com')

Im getting error:

C:\aprog>testff

I think the official answer is found in documentation.

Presently that is:

# Custom profile folder to keep the minidump files
profile = tempfile.mkdtemp(".selenium")
print("*** Using profile: {}".format(profile))

# Use the above folder as custom profile
opts = Options()
opts.add_argument("-profile")
opts.add_argument(profile)
opts.binary = "/Applications/Firefox.app/Contents/MacOS/firefox"

driver = webdriver.Firefox(options=opts,
    # hard-code the Marionette port so geckodriver can connect
    service_args=["--marionette-port", "2828"])

To start Mozilla Firefox with a specific Firefox Profile through Selenium 3.4.3, geckodriver v0.18.0, Mozila Firefox 53.0 and Python 3.6, you need to create a separate Firefox Profile with the Firefox Profile Manager as per the documentation here.

I have created a Firefox Profile by the name debanjan. This profile got stored in this subdirectory:

"C:\Users\AtechM_03\AppData\Roaming\Mozilla\Firefox\Profiles"

The name of the profile (folder) is w8iy627a.debanjan. So while initiating the WebDriver instance we have to pass the absolute path of the Firefox Profile named as w8iy627a.debanjan as follows:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary("C:\\Program Files\\Mozilla Firefox\\firefox.exe")
profile = FirefoxProfile("C:\\Users\\AtechM_03\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\w8iy627a.debanjan")
driver = webdriver.Firefox(firefox_profile=profile, firefox_binary=binary, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
driver.get('https://google.com')

Let me know if this answers your question.

Always use double backslashes in the path (for Windows paths at least):

profile = webdriver.FirefoxProfile('C:\\Users\\Administrator\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\kvycjolb.Prree')

In your code, you use both backslashes and forward slashes.
