How to clear cookies?

[arildojr]

Hi,

How do I clear cookies?
I do need to clear cookies from a URL but in console is always shown:
[ERROR] : chromium: [ERROR:socket_libevent.cc(122)] bind() returned an error, errno=98: Address already in use
[ERROR] : chromium: [ERROR:unix_domain_server_socket_posix.cc(90)] Could not bind unix domain socket to br.com.digipronto.ChinaInBox_devtools_remote (with abstract namespace): Address already in use
[ERROR] : chromium: [ERROR:devtools_http_handler.cc(224)] Cannot start http server for devtools. Stop devtools.

Thanks
