Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.

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

Thank you but it was of no help.

Thank you but I have tried all those suggestions under both 8 and 9. No change.

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, the permissions.default.images pref should be 1.

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

Thank you but I have tried all your suggestions, several times, and everything checks ok, This very FF reply page is missing the icons for the text options, bold, italic, insert link, numbered list, bulleted list; etc. The cursor will indicate their presence and they will function but there are no icons.. TOOLS, PAGE INFO, MEDIA shows one icon and 6 images (png). Nothing blocked, no exceptions.........

If you see the images in Tools > Page Info > Media then an extension may be preventing them from showing.

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).

• Don't make any changes on the Safe mode start window.

I do NOT see the images in Tools > Page Info > Media

Can you decipher it for me? Was it fixed?

Thanks much.

I tried all the solutions mentioned and my settings all match what is selected. Some sites have their page and bookmark icons displayed, others don't.Some that displayed just fin under ff8 & 9 now don't under ff10. Other quit under ff9. Did Mozilla hire Redmond programmers to include this as a feature?

You can use these steps to check if images are blocked:

• Open the web page that has the images missing in a browser tab.
• Click the website favicon (How do I tell if my connection to a website is secure?) on the left end of the location bar.

• Click the "More Information" button to open the "Page Info" window with the Security tab selected (also accessible via "Tools > Page Info").
• Go to the Media tab of the "Tools > Page Info" window.

• Select the first image link and scroll down through the list with the Down arrow 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.
