First off, I'm not sure if this is a Firefox problem or a Facebook problem.

I use Messenger regularly to talk to my friends. At first, it happened on both Chrome and Firefox, I un/installed both of them and the website started working again on Chrome.

I've deleted cookies multiple times on Firefox and before uninstalling both browsers, I even checked Internet Explorer to check if it worked, and it did.

I want to know what happened, why it happened and how I can fix it. Thanks to anyone reading for taking your time out to read my problem.
