Google Maps suddenly displaying black

Google maps displays a map and then, a few seconds later the map goes black. I found an archive thread called "Google Maps suddenly displaying black" where it is suggested to use ctrl+F5 to bypass the cache. That solution works but then, a few seconds later: Boom, the map goes black. Seems to me that when the page is refreshed by a script in the map that whatever gets downloaded corrupts the map and then when the refresh occurs, the map goes black. What ever this "corruption is" Firefox fails to display the content correctly. I have killed my cache, disabled extensions, used troubleshooting mode, switched to the "auto" system theme etc. The key combo is the only way to temporarily recover the map. I should also point out that I see differences in the map UI, it looks like Google updated the UI in maps.
