can only manually resolve "connection is not secure" at secondary level after specifying profile

[FHankey]

Running Windows 7 Professional, Python 2.7, Selenium 3.0.1, Firefox 49.0.1

I'm using Python to start up Firefox and log into our intranet (which is self-signing). I've put in the latest gecko driver (which lets me connect)

When try to simply connect to our internal web

from selenium import webdriver

from selenium.common.exceptions import TimeoutException

from selenium.webdriver.common.by import By

from selenium.webdriver.support.ui import WebDriverWait 

from selenium.webdriver.support import expected_conditions as EC 

driver = webdriver.Firefox()

driver.implicitly_wait(30)

driver.get("https://<my internal ip>/")

I immediately get "You connection is not secure". I click on Advanced | Add Exception | Confirm Security Exception, but then next time I run the script I get the same result. 

I found some suggestions on line. I manually started Firefox, added the Security Exception and located the profile, which appears to be:

    C:\Users\fhankey\AppData\Local\Mozilla\Firefox\Profiles\gppuxlji.default

I modified my script to reference this profile.

fp = webdriver.FirefoxProfile('C:\Users\\fhankey\AppData\Local\Mozilla\Firefox\Profiles\gppuxlji.default')

fpsetting = fp.accept_untrusted_certs

driver = webdriver.Firefox(fp)

driver.implicitly_wait(30)

driver.get("https://<my internal ip>")

This gets me to the main screen (progress), but when my script executes the next steps:

try:

    element = WebDriverWait(driver, 2).until(EC.presence_of_element_located((By.LINK_TEXT, "QA Trunk (QA_Release_V130)")))

finally:

# the page is ajaxy so the title is originally this:

    print driver.title

driver.find_element_by_link_text("QA Trunk (QA_Release_V130)").click()

I get another "connection is not secure". I can manually clear this, but it happens every time. Is there a way around this? 

Thanks
