Selenium Webdriver is detectable
问题 I read everywhere that it is not possible for websites to detect that a user is using a selenium webdriver... but why? For example the webdriver plugin in firefox adds an 'webdriver attribute' to the <html> element. So the <html>... goes to <html webdriver="true">... I am confused... why it is not possible to detect the webdriver? I wrote a little Javascript to get the document.outerHTML... and there is the webdriver attribute! = detected!? Here is my code I tested in Browser with Webdriver
