title: Is there a delete_all_cookies() for ALL domains in Selenium / Chrome?
body: <p>I'm using Python to automate Chrome with Selenium and Chromedriver. I specify a <code>user-data-dir</code> so that the browser has a persistent cache. The problem then is that it also persists cookies and I'd like to delete them <em>prior</em> to each automation run. The only reliable way I have found to do this is to delete all the records from the SQLite3 database <code>$USER_DATA_DIR/Default/Cookies</code>.</p>
  
  <p>There is a method in Selenium webdrivers called <code>delete_all_cookies()</code> but it only removes cookies for the domain of the current URL!</p>
  
  <p>Is there a better method or perhaps a command I can send ChromeDriver that will clear <em>all</em> cookies? Alternatively, is there a setting I can configure which will cause Chrome to remove cookies when it exits and/or starts up?</p>
