Selenium crashing with selenium.common.exceptions.WebDriverException: Message: newSession
Solution 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
Solution 2
Thanks @skyfail. Your answer helped me. The following sequence was performed and resolved the issue.
To upgrade selenium run:
sudo pip3 install selenium --upgrade
To upgrade geckodriver follow steps 1-3 from this
-
sudo mv geckodriver /usr/local/bin/geckodriver
, /usr/local/bin is usually in your PATH so no need to edit it.

Has anyone faced this issue before and has a possible solution ?
UPDATE : Ran the following command :
geckodriver --log trace & curl -d '{}' 127.0.0.1:4444/session

skyfail over 5 years
netstat -tulpn | grep -i 4444
gives me the same output that you're getting. -
fzbd over 5 yearsJust to rule out other instances of the driver, can you run a
killall geckodriver; killall firefox
and try binding to a different port? If you still hit an unavailable address,strace
should output-1 EADDRINUSE (Address already in use)

fzbd over 5 yearsI also edited the answer with a possible version incompatibility.

Viragos almost 5 yearsI had to also install the latest version of firefox

DovaX about 2 yearsI had multiple geckodrivers in my PATH environment, it helped me to delete the old ones
