and it is not working, have manually re-entered my emails/pw's and it still does not function. Also the ability to choose whether it is ative or not is not there, please fix.
Am aware there is a 'not working in FF 50 subject up already, but that 1 is for when it was 'pre-release', this is for the released for regular update version of FF
3.5.23
Apparently you can still use XN 3.5.23 (on FF 50 released version), which you can still get here:

The developer is attempting to keep up with multiple newer versions of FF 50+ via XN 4.x, so...
(FF 50 release version just appeared in last day or so. FF 50 changed their software engine; it is substantial change.
And I see there is now a 51 beta.)
You can install older versions of FF, such as 49.0.2, and turn off updates ...which may be unwise, but see the following:
