Facebook wont fully load

[AllyssaAnderson]

Hey guys! My facebook has been acting up lately. I run on Firefox and up at the corner of the tab the green wheel just keeps going going! It refuses to load pictures as well. Some will load but some wont. The pictures that dont load are just a box with a little paper icon on the left hand corner. Its been happening for 3 days now and Ive a few things that other forms have suggested and nothing is working. I dont have virus protection software (I know) and my operating system is Windows 7. I have a HP 2000 laptop. Its just facebook thats doing this, every other web page is fine. I also have Malwarebytes Anti malware and I used it and remove what it said to.
