You are using an unsupported command-line flag: --ignore-certificate-errors. Stability and security will suffer
Question: I am getting this error in multiple Selenium Python projects when chromedriver
loads. They all start with these imports in case a specific library of
selenium...

    
    
    from selenium import webdriver
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    

Recently I upgraded to Python selenium package 2.42.1, not sure if it is
specific to those updates or a chromedriver thing? Has anyone else seen this,
are there any documentation, and what if any are the potential problems.

I have found this on Windows 7 and Windows 8 OS's.


Answer: There have been many tickets raised in ChromeDriver issue tracker.

Here's the main one:

[Chrome starts with message "You are using an unsupported command-line flag:
--ignore-certifcate-errors. Stability and security will
suffer."](https://code.google.com/p/chromedriver/issues/detail?id=799)

Please keep an eye on it for the latest progress.
