I put this one https://github.com/hultmann/multifox/releases/tag/3.2.3 also downgraded to 52.0.2 FF and still doesnt work, but got even a error. Should i run FF only in 32 bit mode and maybe some other version?
From witch date it started not working? Heres list of updates.

It seems to work fine Basilisk (based in FF52.9).
In Waterfox(based in FF56) and using a new non-e10s window. Although the profile icon displays a kind of error symbol, it also seems to work.
