weathertechdealer.ca doesn't load on Firefox.

edit

It loads fine one Chrome. But no luck on Firefox (or Edge for that matter) I am new to wireshark. Checking the packets in wireshark shows 'Encrypted Alert (1)' and right after Client sends 'Application Data'. After the Encrypted Alert, FINS are acknowledged between the client and server. On firefox, the site is not loaded but just keeps on spinning.

Please help
