Cannot access Namecheap.com using Firefox 51

[horusprim]

For a long time, I have not been able to use FireFox on Namecheap.com. I have all ready updated all Firefox, plugins, and extensions. Still cannot get Namecheap.com to work. Disabling all extensions and add-ons did nott make a difference.

Namecheap.com pages just load indefinably without ever displaying any content. I have to use IE 11 to do anything on Namecheap.com.

Does anyone else have trouble using FireFox on Namecheap.com?
