Answer 1

Try to downgrade firefox:

• https://ftp.mozilla.org/pub/firefox/releases/
• https://ftp.mozilla.org/pub/firefox/releases/49.0b9/win64/en-US/
• https://ftp.mozilla.org/pub/firefox/releases/49.0b9/win32/en-US/

Try using a different driver, chrome, edge, IE, opera.

Basically, try downgrading selenium along with the drivers until you find a version that works possibly selenium==2.53.6 and firefox==46.x

Once you find a version that works, be extra sure to save a profile that has autoupdate turned off, and then use it, or just turn it off everytime:

from selenium import webdriver

profile = webdriver.FirefoxProfile()
profile.set_preference('app.update.auto', False)
profile.set_preference('app.update.enabled', False)
profile.set_preference('app.update.silent', False)
downgraded_firefox = 'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe'
binary = webdriver.FirefoxBinary(downgraded_firefox)
driver = webdriver.Firefox(profile, firefox_binary=binary)

See example of profiles:

• Setting selenium to use custom profile, but it keeps opening with default
• Stopping auto update of Mozilla Firefox

If you click on View problem details of the popup, you might find similar information on why firefox crashed. See:

Answer 2

This is error happens at windows server 2012 and windows 8. It is already reported here . Downgrading to firefox 48.0.2 should fix it

Answer 3

I had this issue with Selenium 3.5 and firefox 54, when setting my own FirefoxProfile instance, for example:

var firefoxOptions = new FirefoxOptions() { Profile = new FirefoxProfile() };

This looks like a bug in Gecko / Firefox / Selenium, the workaround was setting "browser.tabs.remote.autostart.2 = false" in the firefox profile preferences. For example:

var firefoxService = FirefoxDriverService.CreateDefaultService();

var firefoxProfile = new FirefoxProfile();
firefoxProfile.SetPreference("browser.tabs.remote.autostart.2", false);

var firefoxOptions = new FirefoxOptions() { Profile = firefoxProfile };

using (var webDriver = new FirefoxDriver(firefoxService, firefoxOptions, TimeSpan.FromMinutes(1)))
{
    webDriver.Navigate().GoToUrl("http://www.google.com");
}
