I don't know how the Firefox package is built on NixOS, but I just run the one from Arch Linux with the following environment variables:
MOZ_WEBRENDER=1 MOZ_USE_XINPUT2=1 GDK_BACKEND=wayland
That said, the problem occurred for me when using the NixOS package firefox-wayland. It is possibly better to use upstream firefox with Wayland, but I have not tried; I am just running firefox on Xwayland for now.
