Great Post. I set the refererheader to 1 and tweaked the other settings you recommended and already see faster browsing.
network.http.sendRefererHeader - This setting controls whether or not Firefox will send a "referer header" for the pages and files it requests. Sending the referer header takes time, actually more time than you might think. Turning it off can improve your browsing speed quite a bit. The default for this one is '2', which means Firefox will send the referer header for page requests AND for images. Set this preference to '1' to send a referer header for page requests only (faster), or to '0' to not send referer headers at all (fastest).
WARNING: Disabling the referer header can cause some websites not to work correctly; for instance, Buy.com
Would this disable affiliate links that I clicked on from working? or make the tracking so that affiliate links would not be paid?
I am also curious if there is a thread on how to block referrers that come up blocked.
