Firefox Network Tab-Calculate Finish Time

Question

I want to calculate the finish time which we get in the Network Tab/Panel of Firefox ? Any API or any approach used for calculating it is appreciated. Finish time and not only load time. Finish Time as shown in the image

Answer 1

This can be accomplished by the difference between navigation start and load event end:

from selenium import webdriver

driver = webdriver.Firefox()
driver.get('https://stackoverflow.com')
load_time = driver.execute_script('return performance.timing.loadEventEnd - performance.timing.navigationStart;')

This will give you the load time in milliseconds
