Fasterfox - performance and network tweaks for Firefox.

• Prefetch Links
  Dynamic speed increases can be obtained with Fasterfox's unique prefetching mechanism, which recycles idle bandwidth by silently loading and caching all of the links on the page you are browsing.
  
• Tweak Network
  Fasterfox allows you to tweak many network and rendering settings such as simultaneous connections, pipelining, cache, DNS cache, and initial paint delay.
  
• Page Load Timer
  A millisecond accurate page load timer tests the effectiveness of your settings.
  
• Block Popups
  A popup blocker for popups initiated by Flash plug-ins is also included.
  
• Locales included for Chinese, Czech, Dutch, English, Finnish, French, German, Hebrew, Italian, Japanese, Korean, Polish, Slovak, Slovenian, and Turkish. LINK
