i wrote a python code using selenium to interact with a headless browser. Now I'm trying to transfer the program to my raspberry so I don't have to keep my Laptop online all the time. I altered the code a little for the use on the raspberry. The code for the PC works fine, but on the raspberry it stops to respond when trying to click on the button on the webpage. After a few minutes i get the following timeout error:

`  File "AntenneReduced.py", line 52, in <module>
    element1 = WebDriverWait(driver, 30).until(EC.element_to_be_clickable((By.ID, "gl-pl-pause")))
  File "/home/pi/.local/lib/python3.5/site-packages/selenium/webdriver/support/wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message:


During handling of the above exception, another exception occurred:

`The code:

    #!/usr/bin/env python

#binary = FirefoxBinary('/home/pi/Dateien/usr/bin/firefox')

display = Display(visible=0, size=(800, 600))
display.start()

driver = webdriver.Firefox(options=opt, executable_path='/usr/bin/geckodriver')
print("driver geladen")

print("Seite laden geht")

try:
    element1 = WebDriverWait(driver, 30).until(EC.element_to_be_clickable((By.ID, "gl-pl-pause")))
    print("Button ist schon geklickt")

except:
    element = WebDriverWait(driver, 30).until(EC.element_to_be_clickable((By.ID, "gl-pl-play")))
    element.click();
    print("Button klicken geht")

# In[25]:
demo_div = driver.find_element_by_css_selector(".player__song > span:nth-child(2)")

driver.quit()
display.stop()

After the timeout it only has a slow response to commands until reboot.

I'm using a Raspberry3 B+ headless, python3 V3.5.3, Mozilla Firefox 52.9.0 and geckodriver V17
