Selenium: FirefoxProfile 异常无法加载配置文件

小开

最佳答案

Update:

Selenium team fixed in latest version. For almost all environments the fix is:

pip install -U selenium

Unclear at which version it was fixed (apparently r13122), but certainly by 2.26.0 (current at time of update) it is fixed.

This error means that _wait_until_connectable is timing out, because for some reason, the code cannot connect to the webdriver extension that has been loaded into the firefox.

I have just reported an error to selenium where I am getting this error because I'm trying to use a proxy and only 2 of the 4 configured changes in the profile have been accepted by firefox, so the proxy isn't configured to talk to the extension. Not sure why this is happening...

I had the same issue after upgrading Ubuntu to 12.04.

The issue was on the package side and has been fixed in the latest version of the library. Just update the selenium library. For almost all Python environments this is:

pip install -U selenium

If you are running webdriver from cygwin, the problem is that the path to the profile is still in POSIX format which confuses windows programs. My solution uses cygpath to convert it into Windows format.

in this file/method: selenium.webdriver.firefox.firefox_binary.launch_browser():

replace:

    self._start_from_profile_path(self.profile.path)

with:

    from subprocess import Popen, PIPE
proc = Popen(['cygpath','-d',self.profile.path], stdout=PIPE, stderr=PIPE)
stdout, stderr = proc.communicate()
path = stdout.split('\n', 1)[0]


self._start_from_profile_path(path)
#self._start_from_profile_path(self.profile.path)

Since Python is not even close to my primary programming language, if someone can recommend a more pythonic approach maybe we can push it into the distribution. It sure would be handy if it worked in cygwin right out of the box.

As an extension to Jeff Hoye's answer, a more 'Pythonic' way would be to subclass webdriver.firefox.firefox_profile.FirefoxProfile as follows:

class CygwinFirefoxProfile(FirefoxProfile):
@property
def path(self):
path = self.profile_dir
# Do stuff to the path as described in Jeff Hoye's answer
return path

Then, to create your driver:

driver = webdriver.Firefox(firefox_profile=CygwinFirefoxProfile())

I faced the same problem with FF 32.0 and Selenium selenium-2.42.1-py2.7.egg. Tried to update selenium, but it is already the latest version. The solution was to downgrade Firefox to version 30. Here is the process:

#Download version 30 for Linux (This is the 64 bit)
wget http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/30.0/linux-x86_64/en-US/firefox-30.0.tar.bz2


tar -xjvf firefox-30.0.tar.bz2
#Remove the old version
sudo rm -rf /opt/firefox*
sudo mv firefox /opt/firefox30.0
#Create a permanent link
sudo ln -sf /opt/firefox30.0/firefox /usr/bin/firefox

This solved all the problems, and this combination works better !

pip install -U selenium

I had this same issue with Firefox 34.0.5 (Dec 1, 2014) and upgrading Selenium from 2.42.1 to 2.44.0 resolved my issue.

However, I've have since seen this issue again, I think with 2.44.0, and another upgrade fixed it. So I'm wondering if it might be fixed by simply uninstalling and then re-installing. If so, I'm not sure what that would indicate the underlying problem is.

This is not a proper solution but worked for me, if somebody can improve I would be glad to know. I just run my script as root: sudo python myscript.py. I guess I can solve by changing the profile default file or directory could work.

I had the same problem and believed it was the wrong combo of selenium / Firefox. Turned out that my .mozilla/ folder permissions were only accessible to the root user. Doing chmod 770 ~/.mozilla/ did the trick. I would suggest making sure this is not the issue before troubleshooting further.

If pip install -U selenium doesn't work (it didn't, in my case), try downgrading your Firefox to a previous version.

I had Firefox 49.0 and downgraded to 45.0 to make sure the version is supported by selenium. It worked perfectly then.

Here's a fast way to downgrade to Firefox 45.0:

sudo apt-get install firefox=45.0.2+build1-0ubuntu1

Hope this helps.

I was using selenium 2.53 and firefox version 55.0. I solved this issue by installing the older version of firefox (46.0.1) since selenium 2.53 will not work for firefox version 47.0 & above.
