It's not just Firetune, I've seen several windows tweak guides recommending this same switch. Funnily enough, even a few Firefox guides do - that's probably how Firetune picked up the tip too.

Actually, now that I think of it, the biggest placebo/misunderstood setting in Firefox is nglayout.initialpaint.delay

@ author Wow, thanks for that useless piece of information! Go rant in your crappy blog about it but keep trash like this out of W2S!
