Works fine for me in Fx55-56 Rated 5 out of 5 stars
With so many grumpy negative comments directed at the writer of this add-on about the last few weeks of one of my favourite add-ons, I would like write in support of the creator and to note that my installation is still working fine in Fx55-56.
Given that even with Legacy dropouts I've still got close to 100 add-ons, I'm almost surprised that so much is still working fine,
Perhaps those with problems should look elsewhere, rather than throw downgrade the add-on, or abuse the creator.
I also noted the 'new' feature in Fx57 Nightly that seems so familiar, and was noted by another reviewer.
