  2. Click the More information… button in the prompt. The Page Info window will open.
  3. Select the Permissions panel.
  4. Make sure Allow is selected next to Load Images.
  5. Close the Page Info window.

Security software

Some Internet security software (including antivirus and anti-spyware programs, firewalls, privacy programs, and others) may identify and block certain images as web bugs or may prevent images from animating. Check the settings for your Internet security program to make sure it allows images to load.


Extensions are add-ons that add or modify Firefox features. See the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for instructions on how to disable or uninstall extensions that may cause images not to load in Firefox.

Images load but look wrong

If images on websites load, but don't look right or don't look the way they do in other browsers:

  • If you are using any sort of web accelerator software, disable it and see if images load properly. For more information, see the documentation that came with the software.
  • If the image area shows text or some form of gibberish, see the MozillaZine Knowledge Base article Page displays as gibberish.

Other reasons why images may not load

  • The site that displays the images may be down or experiencing difficulties. To verify, try loading the site from a different computer or browser.
  • Some pathnames to images contain backslashes (e.g.\MyImage.jpg). In browsers other than Internet Explorer, these pathnames do not load. If you see that the image's URL contains a backslash, contact the site's webmaster about the issue.

  • You may have modified one of your Firefox preference settings which is causing images not to show. You can either reset all preferences or else try the following:
  1. In the address bar, type about:config and press EnterReturn.
    A warning page may appear. Click I accept the risk!Accept the Risk and Continue to continue to the about:config page.
  2. Find browser.display.document_color_use in the list of preferences. Its value should be set to 0 by default.
  3. Right-clickHold down the control key while you click on the preference if its value is other than 0 and select Reset.
