When you search on a supported engine, FastWeb checks if any results have known alternate domains or mirrors. If so, a compact panel appears with direct links — saving you clicks and helping you reach the right site faster.
The hover warm-up (enabled by default) pre-establishes connections to destinations when you hover over links, making page loads noticeably faster.
