It might just be a corrupt cache file or site cookie. Try clearing your cache and facebook cookies. See

I already have firefox set to auto clear cache and cookies.

Okay, we'll need some more info. You said that none of the apps will load. What do you see when you try to access them?

Facebook opens fine. I click on a game and all I get is the side with some of the posts. the circle just goes round sometimes its green sometimes gray. page stays blank.

Sorry for the late response.

We'll need some more info about your Firefox setup. Go to Help > Troubleshooting Information, then click Copy all to Clipboard. Open a reply to this post, and go to Edit > Paste to paste the info from your Troubleshooting Information page.

i unfortunately can't test Firefox with those add-ons. Maybe someone else here can.

If you close Firefox, then start Firefox in Safe Mode, does the problem still occur? To start in Safe Mode, go to Help > Restart with Add-ons Disabled.

If the problem does not occur in Safe Mode, then you can disable your extensions one-by-one until you find out which one is causing the problem. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.

That didn't work either but it has started working again. Thank you for all your help.

Right now, I'm leaning toward your installation of Flash being the cause. Try this:

In the Windows Control Panel, go to add and remove programs and uninstall Flash. Then use the Install the Flash plugin to view videos, animations and games article to help you install Flash. WARNING: Recently, Adobe has started bundling other products in the Flash installer, so watch for checkboxes.
