Abstract: A system and method for navigating through routinely visited web pages with a browser that allows a user to navigate through the web pages using a “Next/Previous” paradigm. The system includes a routine list having at least one routine, each routine including user ordered user specified URLs, means for editing the routine list and its URLs, means for establishing and specifying a routine from the routine list, and means for sequentially moving from one URL in the specified routine to another URL in the specified routine. By specifying a routine from the routine list, the user can visit a desired group of web pages in a desired order. The moving means allows the user to easily navigate from one web page to another web page in the specified routine in accordance with the user specified order of web pages associated with such routine regardless of any spontaneous browsing conducted by the user.
