“Firefox意外退出。”在Python中运行基本的Selenium脚本时

Question

I'm trying to scrape and print the HTML of a page using Selenium in Python , but every time I run it I get the error message

Firefox quit unexpectedly.

I'm new to Selenium, so any help would be greatly appreciated. I'm hoping for the simplest fix possible. Thank you!

My code:

import selenium
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')
print browser.page_source

Answer 1

My experience since the upgrade to Firefox 38.x on Windows a couple of weeks back has been that it has a problem with Selenium 2.45.x. When invoking the browser it produces a "Firefox has stopped working" error which I have to close manually, at which point the test runs. Others have reported similar issues .

The solution that worked for me (apart from manually closing the error each time, which got old after a few days) was to uninstall the latest version of Firefox and downgrade to version 37.0.2 on the machine where I run the tests. Not ideal for security reasons, but OK if you're careful.

Answer 2

Upgrading Selenium from 2.45 to 2.47 worked for me.

Selenium 2.46 fixes support for Firefox 38 (and looks like 39 as well). See the release notes

Answer 3

What version of firefox are you using? firefox 36 started breaking for me with selenium version 2.43.0 . You can upgrade to 2.45 and check. https://code.google.com/p/selenium/issues/detail?id=8399 They mention at the end that there are fixes for ff 36 in 2.45. For ff 37 and beyond I'm not sure. I downgraded my ff to work with the version of selenium I had.
