I can't even use Facebook without it freezing anymore. I'm using containers and locking down on tracking (no umatrix or noscript though) and Facebook literally craps itself everytime I have it open, helps keep me off of it. It must be my exact setup cause I do the same setup on every laptop / workstation and it slows to a crawl, though mobile.facebook.com works just fine... oddly enough. And I know if I use a vanilla browser it works just fine...
