this is the screenshot of my control panel
I think the issue here is that you have an add in installed in Firefox that is blocking any Javascript including our control panel.
To remove this add in follow these steps:
1. Click on the arrow at the top left corner where it says "Firefox".
2. Choose "Add ons".
3. Near the NoScript add-on click on "disable".
4. Choose "Yes, remove all protections" and open again your browser and your control panel.
5. Now you shouldn't have a problem to view your control panel fully.
But feel free to comment here if this didn't work.
Thank you,
