Right click on the facebook page and select "Page Info" and under the permissions tab, make sure that "Block images ..." is not checked.

Next I would try a refresh: The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.

Note: When you use this feature, you will lose any extensions, toolbar customizations, and some preferences. See the Refresh Firefox - reset add-ons and settings article for more information.

To Refresh Firefox:

1. Open the Troubleshooting Information page using one of these methods:
   • Click the menu button , click help and select Troubleshooting Information. A new tab containing your troubleshooting information should open.
   • If you're unable to access the Help menu, type about:support in your address bar to bring up the Troubleshooting Information page.
2. At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
3. Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
4. Click Finish and Firefox will reopen.

Thank you.

I have done as advised in FB (copied below), but there is NO 'Block Images' entry under 'Page Info'. There is a 'Load Images' entry, which is set to Default and 'Allow'. So how do I get FB to display my photos via Firefox, when FB does display my photos via Google Chrome ?

Right click on the facebook page and select "Page Info" and under the permissions tab, make sure that "Block images ..." is not checked.
