Phew! Here's how I solved it on my Windows machine, using Waterfox (the same steps should apply to Firefox):
Went to Goodreads website -> pressed Ctrl+I to open More Info dialog > selected "Security" -> clicked View Certificate -> then on Miscellaneous section: downloaded PEM cert. (there are three inner "tabs" in that about
:certificate page: www.goodreads.com, Amazon RSA 2048 M03 and Amazon Root CA 1. I used www.goodreads.com.)
Then I imported the certs following
these instructions
Code:
certutil –addstore -enterprise –f "Root" c:\cert\www-goodreads-com-chain.pem
certutil –addstore -enterprise –f "Root" c:\cert\www-goodreads-com.pem
Tried downloading metadata. No good. Restarted computer. Tried again... no good!
Then I ran certmgr.msc (winkey + r), went to Trusted Root Certification Authorities -> Certificates -> double clicked the last one on the list www.goodreads.com, and after that I tried again and it worked!!
