FAQ suggests Firefox tweaks and Polipo to make Tor faster
https://www.torproject.org/docs/faq.html.en#WhySlow
"There are some steps that individuals can take to improve their Tor performance. You can configure your Firefox to handle Tor better, you can use Polipo with Tor, or you can try upgrading to the latest version of Tor. If this works well, please help by documenting what you did, and letting us know about it."
I suggest to remove that bullet point completely.
