It did, then came the big rewrite, and nearly all extensions went away. Some eventually came back, but Singlefile never did; there’s no longer any way to save the html of a site you visit. So I keep Iceraven, which still supports the addons that firefox used to.
You know, I always thought Android Firefox always had full addon support. I’ve got uBlock Origin now, and I remember having Stylus/TamperMonkey.
I also use Iceraven but mobile Firefox has support for some popular extensions
