Selenium does't open firefox-CodePudding

I'm trying use selenium and firefox, but it's just open the browser and set this error:

First Possible Solution:

You need to import

from selenium.common.exceptions import NoSuchElementException

Then you can use try except block

try:
  your_element = driver.find_element_by_xpath(".//*[@id='loginForm:username']")
  your_element.click()
except NoSuchElementException:
  pass

Second Possible Solution:

Without importing anything, checking whether that element exist, if it does then it will be clicked

your_element = driver.find_elements_by_xpath(".//*[@id='loginForm:username']")
if len(your_element) > 0:
    elem[0].click()

CodePudding user response：

wait=WebDriverWait(self.driver,60) 
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR,"#loginForm:username"))).send_keys("a")

Generally Firefox is a tad slower than Chrome so your issue may be timing for find elements. What is recommended is waiting for the element to be clickable and then proceeding to send keys to it.
