Love it on Fx ESR; add Pale Moon support? Rated 5 out of 5 stars

I installed it in Firefox 52 ESR and noticed immediately quite a difference in performance. Well done!

Since you do not permit forks, would you consider adding support for Pale Moon (or making a port)? I would love to see the performance enhancements over there, too.

It's not clear to me also that this will install in Fx ≥ 57 because Mozilla is deprecating XUL support, and in fact I believe is going to remove the ability to install full add-ons in lieu of Web Extensions.
