Ok, no need explaining. If you’re gonna try this, you already know what the client-side cert is. To get it, just go to:
https://admin.fedoraproject.org/accounts/home

Please, login and download it. The link for downloading it is located just bellow of the successful login screen.

If you still don’t know how to create a FAS account, just go to:
https://fedoraproject.org/wiki/Infrastructure/AccountSystem

Ok, let’s pretend your cert is located at $HOME.

# import the certificate using nss-tools
pk12util -d sql:$HOME/.pki/nssdb -i ~/fedora-browser-cert.p12

You, probably, need to restart Google Chrome and that's it. If you wanna install Google Chrome, I suggest using their own fedora repo: http://www.google.com/linuxrepositories/yum.html
