Is only this single image missing or other as well on the page?

Do you see this image in Tools > Page Info > Media?

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

You can check for icons on the location bar that indicate that Firefox is blocking content.
You can also check the Net log in the Web Console (Firefox/Tools > Web Developer;Ctrl+Shift+K) for specific errors about this missing image (reload the page via Command+R or click the Reload button).

If images are missing then check that you aren't blocking images from some domains.

• Press the F10 key or tap the Alt key to bring up 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 link 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 check-mark then remove this check-mark to unblock images from this domain.

Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.

Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.

Make sure that you allow pages to choose their own colors.

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

Note that these settings affect background images.

There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

i can see the chart in Tools > Page Info > Media... the permissions.default.image pref on the about:config page is 1... i have attached the files for your reference... the attached file "HSI Plot A" is from firefox - the missing chart info... the attached file "HSI Plot B" is from safari - display with chart info... let me know if you can resolve this issue... cheers,

i have also used the window pc firefox ver 26 to browse the web page and there is no issue to display the chart and info... so the question is why it only happened in imac firefox... please advise... cheers,

For some reason the images aren't present on the server. There is only a thumbnail of the second image.

Did you try Safe Mode to check for issues caused by extension because the image should show if you can see this image in "Tools > Page Info > Media" ?

why the images aren't present on the server when i use the imac firefox?...

why the images are present on the server when i use the imac safari?...

why the images are present on the server when i use the windows firefox?...

how do i use imac firefox in safe mode?...

cor-el, i knew what is causing this problem ... i found one of the adblock is blocking the display of the chart and its info ... why it is blocking this info and allowing other nonsense ad to be displayed... thanks for your help... cheers,
