If the images show in "Tools > Page Info > Media" then you should see the images on the web page as well.

You can check the Web Console ("3-bar" menu button or Tools > Web Developer) if there are error messages about images being blocked.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

This is what I see: http://i.imgur.com/zGbB26L.jpg

It doesn't matter whether I'm logged in or not.

I don't see any alerts when I click Inspect Element. The Rules box shows a few Invalid Property Value things. I have no idea what I'm looking at or what to do with it though.

I do not have any problems with seeing the images.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: "3-bar" menu button or Tools > Add-ons > Appearance
• Do NOT click the "Refresh Firefox" button on the Safe Mode start window

I tried it again (I had done it before) and nothing changed. I still can't see the pictures.

Do you really see the images that show in my screenshot in "Tools > Page Info > Media"?

What element do you get when you right-click such an empty image block and click Inspect Element?
