What is the difference between manually opened Chrome browser and opened using chrome driver

I am using Selenium for automating the chrome browser. When I download the files using automated Chrome browser it gives me a warning,

'This type of file can harm your computer' with keep or discard options.

But when I manually open chrome and download the files from same site, I won’t get any warnings. I know I can disable the warnings using, options.AddUserProfilePreference("safebrowsing.enabled", true);

But my question is why I am getting this warning only in automated window? What is the difference between browser opened using Chrome driver and manually opened browser?

Please help me.

Solution

  • If during your manual download, in your chrome 

    Settings > Advance Settings

Privacy -> Protect you and your device from dangerous sites (is_checked)

    The download warning wouldn't be displayed on your browser.

    On the other hand, not all chrome options are set to the same value during automatic download from your code. Hence you need to specify :

    options.AddUserProfilePreference("safebrowsing.enabled", true);

    List of all command line arguments for chrome driver goes here.

    Note : Though not all of them are certainly of use while using automation and not all of them correspond to a chrome manual setting either.
