Check the image exceptions: Firefox > Preferences > Content: Load Images: Exceptions - See [[Options window - Content panel]] A way to see which images are blocked is to click the favicon (''Site Identification'' icon) on the left side of the location bar. A click on the "More Information" button will open the Security tab of the "Page Info" window (also accessible via "Tools > Page Info"). Open the ''Media'' tab of the "Page Info" window. Select the first image and scroll down though the list with the Down arrow key. If an image in the list is grayed and there is a check-mark in the box "''Block Images from...''" then remove that mark to unblock the images from that domain.
