Nightly are in-development non-production-ready builds, and as such you can't expect that every single add-on out there will work without problems over it all the time, they do introduce new features and potential compatibility-breaking changes, there could also be bugs on the browser itself that breaks extensions.

Hence, i don't think it's sane to rate add-ons based on your experience using Nightly, instead you can look at BMO (bugzilla.mozilla.org) if whatever problem is reported there, that way we can know if it's caused by a bug in the browser or an upcoming compatibility-breaking change.

Hope that helps or brings some light, and thanks for your other reviews btw :-)
