Firefox Doesn't display correctly and is very laggy on sites with CloudFlare DDoS Protection

Question

Since 35.0 and above i have been getting weird behaviour on sites with CloudFlare DDoS protection.
When i open the site in a new window, it takes a really long time and sometimes doesn't display at all and gives me a blank page. and now it just starts to say "New Tab" and i can't hit refresh.
When the site actually loads after 20 something attempts, the site is laggy, any action takes upwards of 20 seconds.
Whenever i try to open something, i get a blank page with the URL at tabs. Whenever i try to like or post anything, it delays by 15-20 seconds.
Site i am trying to use with much failure. http://hypixel.net/
Anyone else having this issue?
