Stockfish 14 and 16 is not available in Firefox Mobile browser in Lichess.org

[chrome pelican]

Hey, Recently I've noticed an error in lichess in mobile browser (such as Firefox). The analysis engine Stockfish 14 and 16 is not available anymore in my mobile browser. But it works fine on firefox on Windows 10.
Can anybody explain why this happened?

thanks for the heads up. firefox mobile shares major versions with its big brother but still doesn't support one of the security features we like to use. the engines should be available again after the next restart.
