python - How to fix Selenium WebDriverException: "The browser appears to have exited" -

-

i got exception when want use firefox webdriver

raise webdriverexception "the browser appears have exited " webdriverexception: message: browser appears have exited before connect. if specified log_file in firefoxbinary constructor, check details.

i read this question , updated selenium, have same problem.

my code :

driver = webdriver.firefox() time.sleep(5) driver.get('http://www.ooshop.com')

update

i read this question

and have error

oserror: [errno 20] not directory exception attributeerror: "'service' object has no attribute 'process'" in <bound method service.__del__ of <selenium.webdriver.firefox.service.service object @ 0x407a690>> ignored

if you're running selenium on firefox 47.0, need update firefox 47.0.1 which not released in ubuntu's main repos.. have add ppa: https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/ppa

release notes: https://www.mozilla.org/en-us/firefox/47.0.1/releasenotes/

"selenium webdriver may cause firefox crash @ startup"

once firefox 48.0 out, include fix. think ubuntu has skipped update because affects few users.

i can confirm error ff 47.0 , selenium 2.53, , can confirm upgrading ff 47.0.1 fixes error.
