Did you try opening this website with any other browser (like crome, UC, opera)? Are you facing the same issue with other browser too? Did you face this problem with previous version of your firefox (make sure you are using the latest version of the app). if this problem occurring just with firefox then try- 1) clearing the cookies, cache, history 2) Reinstall I hope the above two things will help to resolve your problem.
