I used to have photos and icons but now none are displayed, just text. I deleted Firefox and downloaded but the error continues so I must have a setting wrong.
Go to Solution.
If images are missing then check that you aren't blocking images from some domains.
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, the permissions.default.image pref should be 1.
There are also extensions like Adblock Plus (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.
What photos and icon are you referring to? Pictures and icons on web pages or on the Firefox browser?
