If you open Firefox and go to Help on the toolbar, choose Firefox Help, on the right you will see Ask A Question. This will take you to their support page. At the bottom left, you will see ask a question where you can type in a question or use the chat feature. Or if this is too many steps, just use this link. By the way, when you first click on Help --> Firefox Help, you will see a cat with a sthethoscope. She is looking for an MA job and will travel.

By the way, support consists completely of volunteers. On the top right of the first Help page, there is a place to register and make a contribution. I would consider that if they are able to help you.
