Hi tizzlef,

Have you looked at the Knowledge Base article Fix problems with Facebook games, chat and more? There is a lot of good troubleshooting information in there. Please be sure to try all of the suggested steps. Each one is valuable and may be the answer to your issue.

Hopefully this helps!

Yes, it was the first thing I stumbled upon when finding the Mozilla Help page.

As for the noted Solutions for the "Problems using Facebook in Firefox": I can not access Flash in-game because it takes me straight to a login page. I upgraded Firefox. I cleared Cookies and Cache and History (my browser is set to clear cache and history every time I close Firefox). I updated Java and Java has always been enabled. I disabled old plugins but none that affect Facebook. And ran anti-virus and anti-malware software.

I checked to see if any of those helped after I performed each one... still have the same problem.

Have you tried contacting Facebook? They sometimes roll out experimental changes to a subset of their userbase and this can cause weird behavior on some accounts.

I used my roommate's computer. Logged on to my Facebook account with Firefox and all the applications worked.

I found the fix. Somehow the cookies for "apps.facebook.com" became Blocked. DOH! Unblocked it and everything is back to normal. Thanks.
