If your just aren’t satisfied with your current Internet speeds and can’t afford a faster connection at the moment, then the Fasterfox extension is just for you. Fasterfox uses a variety of methods to increase browsing speeds, including a unique prefetching system which uses idle bandwidth to load and cache the links on the webpages you are currently using. Fasterfox is fully compatible with all Firefox versions from 1.0 to 1.5.0.* and weighs in at a tiny 91kb.

Fasterfox allows the user to choose between 3 optimized settings or customize the settings to their own preferences and can be found from within Firefox’s Options (Tools > Extensions > right click on Fasterfox > Options). This extension also comes with a built in pop-up blocker which, in my opinion, is very handy.
