Hi curiouskid,

You do not appear to be posting this from Firefox. Are you having other problems also with Firefox ? We will probably need more details of your Fireox setup.

Please

1. give examples of site where this happens. (Please give links that we can use and test not ones behind paywalls or other logins)
2. Paste your trouble shooting info into a reply.
   • Obtain it from: FirefoxButton -> Help-> Troubleshooting Information
   • see Use the Troubleshooting Information page to help fix Firefox issues
   • edit out the print information if you are running short of space.

Thanks for your reply. (1) Firefox on my desktop primary browser. Example of error. Go to cnn.com. Pick a story. Decide to email it to someone. To activate email, you are asked to type the letters you see in the box. The box is always empty. Today I'm am trying to build a wesbite on squarespace. It also needs me to type the letters in the box but the box is empty. This does not occur in either situation when I use Internet Explorer, which is a rarely uses alternate browser for me. (2) I will now also check out troubleshooting information page on FireFox

I do not actually see a 'captcha presenting letters to identify and input when I try the link cnn.com . I get the page http://edition.cnn.com/ it does have a facebook login link on it that is all I see. Maybe I am already registered on cnn or it is on a different page.

1. Are you able to give another couple of examples please ?
2. I await your troubleshooting information.
3. Your system details aside indicate a User Agent String
   User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.57 Safari/537.36 I would expect that to be because you were using the Chrome browser. (If not the change causing that could have unexpected effects on your Firefox use)

Meanwhile you my wish to look at these articles

• Fix problems that cause images to not show
• Websites look wrong or appear differently than they should

Thanks for hanging in. My day job interrupted. Example -1.

(1) Go go www.cnn.com. 
(2) Pick a story line.  Right now --"Fight Club Producer: I was Israeli Spy." 
(3) Click on it to go to the story. 
(4) In upper right corner there is an option to email the story. 
(5) click on that. 
(6) at the bottom of the email info pop-up is the captcha to fill in. Mine is always blank. This has been the case long before Chrome arrived.  
Example 2. 
Follow this link to Square Space - http://five.squarespace.com/signup 
(2) click on option to use squarespace 5. 
(3) fill in info to set up website - only 4 lines. 
(4) click and you will get a captcha to fill in. Followed by "create Website" which you do not want to click on. My captcha is empty.

SquareSpace is using Google's reCAPTCHA service. Do you use any extensions that block/filter content to protect your privacy or reduce annoyance? To see whether an extension is a likely culprit, try the page in Firefox's Safe Mode. That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

In example 1, that is an image coming from Google:

• http://www.google.com/recaptcha/api/image

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

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.
