fx_pnh.xpi can't be installed in Firefox 48.0.1

I'm getting the error message "This add-on could nto be installed because it has not been verified" while installing the add-on. Hasn't to.his been submitted and reviewed by Mozilla? If it has already been reviewed and approved, please let me know the solution or workaround if any.

@marlonbriguera You need a Firefox nightly build or Firefox developer edition to install this addon as it is based on some obsolete APIs which are not supported in recent versions of Firefox.
