Overall great for doing exactly what it says: It cuts down on the tracking that Facebook and its affiliate websites carry out, including links on other websites. My only problem that I've had personally is that there is some odd glitch that occurs due to the Container that causes the tab to flicker, opening and closing itself in a repetitive loop. I have yet to figure out a means to stop this happening, and as such have pretty much just stopped using all of Facebook's sites entirely except for occasionally poking at the Instagram app on my phone.
