1. A method , comprising: tracking a first text input to a text field using a computer processor, the text field functioning to direct network navigation operations of a web browser; consulting a set of probability data to determine a most likely network navigation destination using the text input; determining a confidence value for the most likely network navigation based on a hash value, the hash value comprising one or more links associated with a navigation history of a user, wherein the user is granted access permission to data from the one or more links; and prerendering the most likely network navigation destination using the web browser, wherein the confidence value for the most likely network navigation exceeds a configurable threshold value; generating the set of probability data by a method comprising: monitoring one or more previous text inputs to the text field; displaying one or more potential network navigation destinations associated with each of the previous text inputs in response to the one or more previous text inputs; and storing selection data indicating whether the displayed one or more potential network navigation destinations were selected, the data associating each of the one or more previous text inputs with the one or more potential network navigation destinations.
