Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Clearing the cache and removing cookies did it. The lost cookie caused a request to log in anew. When that was done, the videos started loading again. Who can figure?
