Today in the afternoon, Facebook started to act strangely. I can log on without a problem, but when i'm in the website the home and the profile pages are not visible, they are blank and this is strange because with Chrome i have no problems, and because in the safe mode the problem is still here, so the plugins aren't the source of the problem. The account and other option pages are fine, only those two don't work. Few weeks ago, i had to change a value in the about:config page, to make work "youtube buttons", but i think it's not that the problem, also because this morning Facebook worked. I don't know what to think. Is this maybe Facebook IT fault? Boh. Thank you for your time
