Cannot log in to manage passwords, etc.

Running Win 10 Pro 1607, build 14393.953, FF 52.0.1 (32-bit) and am not having a problem logging into my vault. What I AM having a problem with is logging in to the site, identitysafe.norton.com to manage my logins. Had no problem last week getting in but for the past two days plus, the progress icon just rotates and never connects. Not strictly a FF problem; none will access.

Temporary?
Thx,
