[FIXED] Is there a delete_all_cookies() for ALL domains in Selenium / Chrome?

Issue

I'm using Python to automate Chrome with Selenium and Chromedriver. I specify a user-data-dir so that the browser has a persistent cache. The problem then is that it also persists cookies and I'd like to delete them prior to each automation run. The only reliable way I have found to do this is to delete all the records from the SQLite3 database $USER_DATA_DIR/Default/Cookies.

There is a method in Selenium webdrivers called delete_all_cookies() but it only removes cookies for the domain of the current URL!

Is there a better method or perhaps a command I can send ChromeDriver that will clear all cookies? Alternatively, is there a setting I can configure which will cause Chrome to remove cookies when it exits and/or starts up?

Solution

Chrome supports DevTools Protocol commands like Network.clearBrowserCookies that you can call remotely. Selenium does not have an interface for this because it's not part of any standard.

However, you can add support for these commands by patching Selenium's supported commands like this:

send_command = ('POST', '/session/$sessionId/chromium/send_command')
driver.command_executor._commands['SEND_COMMAND'] = send_command

Now you can call any DevTools Protocol command like

driver.execute('SEND_COMMAND', dict(cmd='Network.clearBrowserCookies', params={}))

This deletes all cookies for all domains.
