K-Meleon
K-Meleon began as a competitor to Mozilla's original internet suite. It had the goal of being faster and lighter. Until 2011, K-Meleon embedded Gecko in a stripped-down interface. Throughout its lifespan, K-Meleon has required small amounts of memory. K-Meleon 76 uses the Goanna fork. It supports platforms no longer supported by Mozilla after their Gecko rewrite. K-Meleon supports older computers and older computer software. It maintains active support for Windows XP and Windows Vista.
