At one point when I was on youtube I was able to see all videos and such but now they aren't showing up. I've checked all my settings and they are fine because other sites I goto I have no issues. As soon as I goto youtube no video thumbs show up and I have to click on them to see them. My other browsers have no issues except this one.

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

  • Press the F10 key or tap the Alt key to bring up the hidden "Menu Bar" temporarily.
  • Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"
  • Check "Tools > Page Info > Media" for blocked images
  • Select the first image link and use the cursor Down key to scroll through the list.
  • If an image in the list is grayed and "Block Images from..." has a check-mark then remove this check-mark to unblock images from this domain.

Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.


Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.

Make sure that you allow pages to choose their own colors.

  • Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"

Note that these settings affect background images.

There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

Did you check in Tools > Page Info > Media if you can find those missing images?
