See [[Images or animations do not show]] and http://kb.mozillazine.org/Images_or_animations_do_not_load It is possible that you accidentally clicked the 'Block Images' item in the right click context menu while trying to save an image. Check the image exceptions: Tools > Options > 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 and click the "More Information" button. This will open the Security tab of the ''Page Info'' window (also accessible via Tools > Page Info). Go to the ''Media'' tab of that Page Info window. Select the first image and scroll down though the list with the Down arrow. If an image 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.
