Fasterfox Lite allows you to easily tweak many network and rendering settings such as simultaneous connections, pipelining, cache and initial paint delay. Unique to this Lite version are included options for SSL Pipelining, timer-based content reflows, UI Responsiveness, Link Prefetching, IPv6 DNS lookups, and by default the Page Load Timer is disabled.

If you want to manually change the "about :config" settings, then the Fasterfox Lite preset must first be saved to the "Custom" setting. This is to prevent the configurations from being different from a selected preset's settings.
