Selenium Firefox Profile无法正常工作

Question

I am trying to load my selenium firefox profile and I keep getting the error:

WebDriverException: Message: Can't load the profile. Profile Dir: %s If you specified a log_file in the FirefoxBinary constructor, check it for details.

The code was working fine 15 minutes ago.. I am not sure what happened.

I have firefox 43.0.4 and selenium 2.49

This is my code that throws an error:

profile = webdriver.FirefoxProfile()
driver = webdriver.Firefox(profile)

I am using Windows 7 Professional, Python 2.7.10 | Anaconda 2.3.0 (64-bit)

Traceback:

Answer 1

Different selenium versions have compatibility issues with certain Firefox versions. Selenium 2.49 and Firefox 43 work together well.

Make sure you are really using selenium 2.49 :

import selenium
print(selenium.__version__) 

Answer 2

I had the similar issue, the issue was after starting virtual display for headless I wasn't stopping it. So all of them were running in background. Run top command and check if there is not browser firefox running after tests are finished.

Answer 3

There are some know issues with profiles. As per the Selenium release notes you shouldn't be using profile = webdriver.FirefoxProfile(profilepath) anymore...
