I am using the full Roots stack and have been developing this way for months without a problem. I recently updated Chrome and it is now stopping me from accessing localhost after I run `yarn start` in Sage. The development server is set to use self-signed certificates and allows me to connect to my .test site (although I do get a Not Secure message).

Is there a way to validate the localhost SSH certificate? I used the vagrant trellis-cert plugin that imported the .test certificate successfully.
