Remember when we want to tweak firefox settings, we have to go through the about:config manually to add parameters? There is a easier way now. Fasterfox is a performance and network tweaks extension for Firefox which allow you tweak many settings within Firefox – such as modifying all those settings for prefetch links and network settings. In addition, there is a built in popup blockers and page load timer to calculate your modified settings. Here are the description for its features:
Prefetch Links: Dynamic speed increases can be obtained with Firefox’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.
Block Popups: A popup blocker for popups initiated by Flash plug-ins is also included.
Page Load Timer: A millisecond accurate page load timer tests the effectiveness of your settings.
