A must-have extension, if you use it correctly Rated 5 out of 5 stars
Folks, stick with the "courteous" preset if you don't understand the implications of changing network settings, and make sure prefetching is turned off. The opposite of "courteous" is "rude", some websites WILL throttle or block you if you open too many connections at once. It's not the extension's fault if you misuse it.
BigRedBrent might want to consider removing or renaming the "turbo" preset, it's probably the reason behind a lot of negative reviews. It's not a magical "go faster" button, more of a magical "annoy webmasters" button.
