Answer 1

Looks like selenium 2.45.0 does not support ff 37.

The change log shows selenium 2.44 supported FF33. Selenium 2.45 was released around Feb 26th 2015, while FF37 was released on March 31st 2015.

Answer 2

Looks like by the time the page loads it is executing this line of code and throwing an error message. try to wait till the page loads by using

time.sleep(200)

and keep this line of code under try block as:

try:
    WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "table.data-list")))
except:
    print("not found")
