Completely not works for me, even after install the component in "windows.zip". Check connection always told me no native client . Windows 7 x64 + FF57
Somehow, I found out that FDM 5.1.33 has been released, as it claims working for FF57. After FDM 5.1.33 installed & enable extension in its setting again, everything works as old day. https://image.prntscr.com/image/VM7RUK25TN6VTN10CmCImQ.png
