Note that some GIF images might be animated GIF images that are actually MP4 files.

Is only the animation not working or don't you see anything at all?

u can check this pref on the about:config page and possibly reset the pref via the right-click context menu to the default value

  • image.animation_mode

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.


If images are missing then check that you do not block images from some domains.

  • you can tap the Alt key or press the F10 key to show 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 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 checkmark then remove this checkmark to unblock images from this domain

You can check these preferences on the about:config page and make sure they have the default value.

  • permissions.default.image (1)
  • network.http.sendRefererHeader (2)

There is Tracking Protection that can block (wanted) content, so check the location/address bar for special icons.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (e.g. Adblock Plus, NoScript, Ghostery, uBlock Origin) always make sure such extensions do not block (wanted) content.

  • make sure your extensions and filters are updated to the latest version

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.
