Selenium Version: selenium==3.6.0

Browser: Mozilla Firefox 63.0

Geckodriver version : geckodr

Answer 1

I fixed the issue by updating the selenium python package and using the latest geckodriver.

Thanks @fzbd for all your help.

Additional context -

Refer to the compatibility chart here - https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html#supported-platforms

update selenium :

 pip install -U selenium

update geckodriver (choose the correct version for your needs based on the above compatibility chart)

Check the versions for all components -

firefox -v
geckodriver -V
pip freeze | grep selenium
