Help getting started?

I am researching several tools and wanted to give this one a try. I am on osx and installed both the stable and master branch with pip3 but I can't seem to get it to work on either latest chrome or firefox. I always get

with google or facebook, I am mostly interested on facebook.

I couldn't even get the certificate out of it to trust it or didn't find the CA Cert to add.

Would this store private access/comments with facebook? what about user interaction?

Start with the traceback in warcprox/mitmproxy.py, especially do_CONNECT and finish_request, and reproduce the reported failure on macOS with Chrome or Firefox. The issue does not name a test or a specific code change; done would require identifying the certificate or proxy failure and documenting or fixing the path to a working browser setup.
