Prompt_for_download is still appearing after setting false in prefs

google-chrome protractor selenium-chromedriver

I think you also need to add directory_upgrade:

prefs: {    download: {        prompt_for_download: false,         directory_upgrade: true,        default_directory: '/tmp/downloads'    },},

Aside from that, make sure /tmp/downloads directory exists and there are permissions to write into it. Also see a similar issue:
