python selenium does not scale with firefox - Message: Can't load the profile. Profile Dir

Why does this happen using selenium with python and firefox? Selenium cant scale to a simple loop. Why cant firefox scale? Over time it decides to thow an error and quit.

Mozilla Firefox 45.0 selenium.version '2.53.2'

from pyvirtualdisplay import Display
display = Display(visible=0, size=(800, 600))
display.start()
mylist = ['page1','page1',...,'pageN']
while True:
   for data in mylist:

        browser = webdriver.Firefox()
        try:
           myfunc(data) # Code that uses selenum to fetch pages
        except:
            pass
        browser.quit()
   time.sleep(60)



No handlers could be found for logger "sentry.errors.serializer"

Selenium is not failing while running the loop, it is failing at webdriver.Firefox(). The error is recognized when the connection times out at a certain time after line 231 when the script still cant recognize an open firefox application.

It is just a bug in selenium when running with a headless browser. To get a working version of selenium, run 

sudo pip install -U selenium

This should be a similar issue: Selenium: FirefoxProfile exception Can't load the profile
