I work at an organization that inspects all HTTPS traffic by injecting its own SSL certificates. It wasn't configured properly though, so Firefox always shows a "Your connection is not secure" error message. Sites that use HSTS do not allow me to see them at all.
This is a problem because I am a developer and I need to download files from the Internet.
git clone becomes
git -c http.sslVerify=false clone, and so forth. This is more than an inconvenience -- it is a security hazard, and it makes it impossible to run certain scripts that do not provide an option for accepting insecure certificates (such as running get-pip.py for installing the Python package manager).
I have looked under the little padlock in Firefox and I don't see a root certificate for me.
Is there any way for me to accept these certificates globally? I have root on my machine.
