History-Tree: Browser plugin uses your browsing history to predict which pages you will visit next. This can help you in two key ways: Let’s say you are currently reading the New York Times. After reading NYT, you always go to the Economist. Once the plugin notices this pattern, it can make this transition seamless. Whenever you press some hotkey, it will show you which websites you commonly browse to next in a small tree. Secondly, the plugin pre-loads these pages, to make them render instantly once you choose to view them.
