Errr... is "dom.enable_performance" really a privacy setting?
Doing someone online searching now, not seeing an explanation for it. There is one other HN post though, also mentioning it in a privacy context, but not further info either. :/

If you asked me "where would you go to change settings to prevent the browser from violating your privacy and infringing on your security?", then, yes, I would go to "Privacy and Security". If, however, you asked me "what would you expect to find under 'Privacy and Security'?", my answer would be that that's where I would go to protect myself from malicious websites, not from malicious browsers.
(I know that 'malicious' is quite, and almost certainly too, strong here, but the point is that I think, and am explicitly encouraged to think, of Mozilla as being on my side against the sites I visit, and I don't think it's natural to expect that I will start thinking of how I need to protect myself from Mozilla to use their products in the way that I, rather than they, intend.)
