Can't open fedora silverblue website in firefox

Why I cannot open fedora silverblue user guide in Mozilla firefox ?
Any thoughts?

Hello @bijikeci,
Welcome to the discussion forum. For user support issues, please go to ask.fedoraproject.org. This discussion area is more for active contributors to Fedora.
As for the SB docs/guide site, it opens fine for me in FF.

@bijikeci The docs infrastructure had some build issues recently that was causing this problem. It should work now.
