Selenium Python (3.141.0, Geckodriver 0.30.0) can't open Firefox Webdriver: "Your Firefox-CodePudding

FIXED: While upgrading Ubuntu 21.04 to 21.10 firefox (previously installed with apt) got removed and installed with the snap-version. Reversing (uninstalling the snap version & reinstalling with apt) this fixed my issue.

I should've investigated after I had to reset firefox to be the default browser after the dist-upgrade again.

When trying to create a Firefox Webdriver with Selenium for Python I get greeted with the following: "Your Firefox profile cannot be loaded It may be missing or inaccessible." And after clicking 'ok' the following stack trace appears:

>>> foo = webdriver.Firefox()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/jonathan/.local/lib/python3.9/site-packages/selenium/webdriver/firefox/webdriver.py", line 170, in __init__

    response = self.execute(Command.NEW_SESSION, parameters)

    raise exception_class(message, screen, stacktrace)

This has not happened before upgrading to Ubuntu 21.10 (from 21.04) but I do not know what could cause this error. Manually trying to create the driver with the old Geckodriver (0.29.1) does not work too and results in the same error:

$ ./geckodriver.bup -V

The only thing I am positive that changed was the python version (to 3.9.7 from 3.9.5, but using a python-venv with 3.9.5 produces the same errors).

Is there a glaring error I am missing?

e2: I suspect the error to be with permissions of the temporary profiles that get created. But the profiles created in '/tmp/' look clean. They are always set to the current user. Specifying them manually with e.g.

foo = webdriver.Firefox(firefox_profile=r'/tmp/rust_mozprofile7nswon')

returns the same error ('Your Firefox profile cannot be loaded. It may be missing or inaccessible.').

CodePudding user response：

Download web driver for firefox : https://github.com/mozilla/geckodriver/releases

then unzip file on default directory

tar -C /usr/local/bin/ -xvf geckodriver-v0.30.0-linux64.tar.gz

Add the chosen geckodriver directory to PATH

export PATH=$PATH:/YourDirectory

Create python file main.py

from selenium import webdriver
browser = webdriver.Firefox()
browser.get('https://google.com/')

run python main.py

Try this way may be help you

CodePudding user response：

tl;dr: Reinstalling firefox (uninstalling the snap package and installing with apt) fixed the problem.

I took SiKings comment to heart and the only answer mentioned "If your Web Browser base version is too old uninstall the Web Browser through Revo Uninstaller and install a recent GA released version of the Web Browser." so I reinstalled firefox which subsequently fixed the problem.

The version did not change:

$ firefox -V
Mozilla Firefox 93.0

I believe this was most likely a permission problem caused by the dist upgrade.
