Firefox Dark Mode to Light mode switch problem

more options

In MacOS Big Sur 11.1 on my MacBook, I have set MacOS to automatically switch between Light Mode and Dark Mode. But I notice that Firefox does not handle this well. When I have used my MacBook Dark Mode and switch back to Light Mode, Firefox still hangs in Dark Mode. The only way to solve this is to choose Light Mode in System Preferences instead of automatic.

The only way to solve this is to choose ''Light Mode'' in ''System Preferences'' instead of ''automatic''.
