I was a Pale Moon some years ago, and because of various factors have not used the Pale Moon browser for quite some time (more than a few years now); primary factor is being on low CPU/RAM netbooks/laptops.
I now have a Chromebook and thought I would try Pale Moon once again after trying out Brave, Opera, and Vivaldi on the Linux Environment of my Chromebook.
I must say that while the Chromium-based browsers seem to have a performance advantage in loading pages a bit more quickly, I find myself endeared with Pale Moon's feel and cutomizability (if that's a word).
I am using a few addons UBlock Origin, Suspender, FireShot, MoonGestures, and Toggle Javascript (Enabled/Disabled).
I am using the LittleMoon Theme to conserve as much vertical space as is possible while keeping all toolbars open.
I have experimented with the Connections Settings a bit in about:config to help with page loading speed which has yielded modest improvement at best for that.
I have also installed a few bookmarklets for easy sharing of links to social media: AddToAny and GabShare; I like the fact that Pale Moon allows me to choose what mail handler to use effortlessly for this purpose as well.
So to Matt Staver (I think that's your name) and any others that might be contributing to Pale Moon the browser and its extensions and themes, I say a very heartfelt thank you ... I am having some good fun browsing again!
