The problem came from the possibility to block the images from a site. I had inadvertently blocked the images from cartoonbox.slate.com while not even knowing this feature exists. I had to surf cartoonbox.slate.com using another browser for almost a year... I believe current versions of Firefox are less prone to this problem occurring and going unattended.
