Does this happen in Firefox Safe Mode? Are you blocking images in any way?

more options

If images are missing then check that you aren't blocking images from some domains.

  • Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
  • Check that images are enabled: Tools > Options > Content: [X] Load images automatically
  • Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
  • Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down 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.

Make sure that you do not block third-party images, the permissions.default.image pref should be 1.

There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

I don't know if i am in safe mode? How does one get into safe mode? How can you tell you are in safe mode. Also i will go to another site called thottbot.com where it shows you maps of location of characters in the game wow. all i ever see is blank box where the map should be just like my black box thumbnails on Utube.
