I hope so. Since the last Dino-Update start that support for libcamera.
I think it will be solved soon. Did not test this and i am not sure about the quality, or how the rights got implemented. But since Firefox support a request and Setting on Video devices and rights it should be fast usable.
My camera Experience is bad, but i still use the stable one, cause i do not need to take pictures or record videos right now with my Librem5.
