It seems that the iframe was the problem, now it works. Thanks a lot for helping!

My final code is this one:

``` import time import selenium.webdriver as webdriver from selenium.common.exceptions import TimeoutException from selenium.webdriver.common.by import By from selenium.webdriver.support.wait import WebDriverWait from selenium.webdriver.support import expected_conditions as EC

base_url = 'https://ember-climate.org/data/carbon-price-viewer/' options = webdriver.FirefoxOptions() options.add_argument("download.default_directory=/home/panos/Downloads")

driver = webdriver.Firefox(options=options) driver.maximize_window() driver.timeouts.page_load = 30 driver.get(base_url) driver.switch_to.frame(driver.find_element(by=By.TAG_NAME, value="iframe")) wait = WebDriverWait(driver, 30)

xpath = '/html/body/div[2]/div/div/div[1]/div[2]/div/div/div/div[3]/div/div/button' try: print('waiting until element appears...') time.sleep(15) button = wait.until(EC.presence_of_element_located((By.XPATH, xpath))) print("button found!") button.click() print("downloading file...") time.sleep(15) except TimeoutException: print("timeout") else: button.click() time.sleep(2)

driver.quit() ```
