Why do some pictures not come through on my Facebook account when I use the FireFox browser? They come through on IE, but not FireFox. Is there anything I can do about it?
The above is great advice. Any ad-blocking extensions or tracker-blocking extensions may be causing this problem.
No guarantee of success, but two things you should do are:
1. Clear the cache and cookies in Firefox (press Ctrl+Shift+Delete, change the time range to "everything", tick Cookies, Cache and Active Logins and click [Clear Now]).
2. Disable all add-ons and see if that makes a difference. If it does, start re-enabling them one at a time until you find which one caused the problem.
