Suddenly on Monday this week, Facebook stopped working on my Firefox for desktop. It loads perfectly fine on all other browsers. Please help!

Hi Kirsten

That looks like an error at the Facebook end. We are not hearing other reports of this at the present time. I recommend leaving it 24 hours and seeing if it is resolved.

Thanks, Paul - it has been like this for three days now, though.

That is strange.

Do you have any add-ons installed in Firefox?

Is your computers operating system and any antivirus software completely up to date?
