Some web sites require you to type words presented in a strange form (Captcha?). The 'Captcha' does not always show up on my screen. How can I fix this?

I do not know how to make this any more clear. The strange, 'squiggly' words are meant to protect a web site from computerized log ins (I think). If the words are interpreted and entered correctly, you can log in successfully. But since the strangely formed words do not show up on my screen, I cannot continue the process. This does not occur all the time, on some sites the strangely formed words show up, and I can continue the process. Is this a problem with Firefox, my computer, or the web site I am trying to log into?

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 permissions.default.images

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


Start Firefox in Diagnose Firefox issues using Troubleshoot 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).
