To boost the performance of FireFox 1.5 or later, you need to install extra add-on named FasterFox provided by Mozilla. To download this add-on, go to

https://addons.mozilla.org/en-US/firefox/addon/1269

FasterFox allows you to tweak many network and rendering settings such as simultaneous connections, pipelining, cache, DNS cache, and initial paint delay.

Dynamic speed increases can be obtained with the unique prefetching mechanism, which recycles idle bandwidth by silently loading and caching all of the links on the page you are browsing. A popup blocker for popup initiated by Flash plug-ins is also included.
