Selenium use of Firefox profile
<p>I try to use Selenium Webdriver and Python on Windows 10 system to make some automation of browser actions. But I have this problem: Selenium-started Firefox window doesn't "see" that I am already logged in and target site sends me to login page. So I assumed that Selenium  not really uses the profile, but just a copy of it.</p>

<p>I would like to know:</p>

<ol>
<li>Is my conclusion about actual use of copy of profile true?</li>
<li>If 1. is true, is there a way to use really everything from existing profile?</li>
<li>If my conclusion is not true, please prove it and point me to the direction where I can find out what information can be used for session, why Selenium could fail to send it and how to force it to do so actually. </li>
</ol>

<p>Edit:</p>

<pre><code>from selenium import webdriver
fp = webdriver.FirefoxProfile('C:/Users/&lt;user name&gt;/AppData/Roaming/Mozilla/Firefox/Profiles/abc3defghij2.ProfileName')
driver = webdriver.Firefox(fp)
driver.get("https://www.example.com/membersarea")
</code></pre>
