Hi, Firefox has been blocking you guys for the last few days, and I don't believe it's my network.
My understanding is that Cisco Umbrella is responsible for The Daily Neopets' root certificate, and something is currently wrong with that certificate.
What's interesting is the dates on it. It became valid yesterday and it's only valid for 5 days (by comparison JellyNeo's certificate is good for 3 months (Sep-Dec) and Neopets's is good for 1 year (Jan-Jan)).
More interesting, though, is the address Firefox is blocking when I try to connect. Attached are the relevant screenshots.
Thanks!
