Cant log onto my fb al account on chrome :/

[Beatmap]

ive been having this issue for a long time. whenever i try to log onto my fb account on al,the "sign in with facebook" button does nothing. Its like the button is not there,it doesnt respond. I have this issue only with fb and the other log in works fine. i would be really greatful if someone tells me how to fix this.
Thanks in advance :)
