I will say as an aside from our discussion, just to stress

I'm not trying to say Firefox is doing bad at performance (I know going through this explaining my setup it may sound that way)

What i'm trying to say is that in response to the original comment

It’s interesting how we all are focusing on tiny non-noticeable performance gains when privacy is what matters in browsers.

To basically say "Nono, performance is important! Please don't stop"

And yes, privacy is also important, Firefox can have both, and I really want to encourage that. Not one or the other.
