Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit") --- Check the image exceptions: Tools > Options > Content: Load Images: Exceptions See Fix problems that cause images to not show and http://kb.mozillazine.org/Images_or_animations_do_not_load

A way to see which images are blocked is to click the favicon (Site Identification icon) on the left side of the location bar and click the "More Information" button. This will open the Security tab of the Page Info window (also accessible via Tools > Page Info). Go to the Media tab of that Page Info window. Select the first image and scroll down though the list with the Down arrow. If an image 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.

I started in safe mode with all plugins disabled and Firefox setting back to default. I still can't see the Amazon links on my blog... Is there a way to go back to an older version of Firefox? The links worked fine before my Firefox update. the links still show fine in Chrome and IE. It is not a problem with my site.

Problem started after Firefox updated my version 11. I have tried both 12 and now 13... same problems. Can I go back to 10?

Do you see the links in the page source if you select that area with the mouse and select View Selection Source in the right-click context menu?
