Python Question

"Can't load the profile" error occured with Selenium WebDriver by Python3.5 and FF48

 I'm trying to use Selenium with Python.

 So, I wrote the following codes and save as the file named test.py in working directory /Users/ykt68/seleniumwork .

[ykt68@macbp15 seleniumwork]$ pwd
[ykt68@macbp15 seleniumwork]$ cat -n test.py

1 #! /usr/bin/env python
2 # -*- encoding: utf-8 -*-
4 from selenium import webdriver
5 from selenium.webdriver.common.keys import Keys
7 driver = webdriver.Firefox()
8 driver.get("http://www.python.org")
9 assert "Python" in driver.title
10 elem = driver.find_element_by_name("q")
11 elem.clear()
12 elem.send_keys("pycon")
13 elem.send_keys(Keys.RETURN)
14 assert "No results found." not in driver.page_source
15 driver.close()

[ykt68@macbp15 seleniumwork]$

 These codes above are the same as 2.1 Simple Usage in documents of Selenium with Python.

 When I ran the python command for test.py above,

  • FireFox browser started and opened a blank tab.

  • And after about 30 seconds have passed, the following error messages were displayed and FireFox window was closed.

[ykt68@macbp15 seleniumwork]$ python test.py

[ykt68@macbp15 seleniumwork]$

 Please teach me why this error has occured and how to solve the problem or list some posts or documents I should refer.

 In addition,

  1. Environments:

    • OS: Apple OS X Version 10.11.6

    • Python Version: 3.5.2

    • FireFox Version: 48.0.2

    • selenium Version: 2.53.6

[ykt68@macbp15 seleniumwork]$ python -V
Python 3.5.2
[ykt68@macbp15 seleniumwork]$ /Applications/Firefox.app/Contents/MacOS/firefox -v
Mozilla Firefox 48.0.2
[ykt68@macbp15 seleniumwork]$ /Applications/Firefox.app/Contents/MacOS/firefox-bin -v
Mozilla Firefox 48.0.2
[ykt68@macbp15 seleniumwork]$ pip list
pip (8.1.2)
selenium (2.53.6)

[ykt68@macbp15 seleniumwork]$

  1. I reffered the similar post of
    Selenium: FirefoxProfile exception Can't load the profile. So I tried

pip install -U selenium

But the situation with error messages above remains unchanged.

Best Regards.

From what I understand and concluded, you can keep the latest selenium package version, but you have to downgrade Firefox to 47 (47.0.1 is the latest stable from the 47 branch).
