There is a known issue in Firefox 70 that prevents some pages or page elements using dynamic Javascript (like YouTube or Facebook) from loading properly.

A Firefox 70.0.1 update was released that should resolve the problem. Please update Firefox to the latest release.

If you are unable to update Firefox, here is a temporary workaround:
