Classifying and organizing web resources in web browsers

A method of presenting information in a web browser, comprising:

• receiving data from a plurality of resources that are accessible from the web browser;
• detecting one or more characterizing features that are part of said received data;
• associating a resource as belonging to a group of resources based on a classification of said one or more characterizing features;
• presenting each group of resources in one of two modes, where in a first mode a browser window is open and information representing a resource associated with the group is displayed, and in a second mode the group of resources is a minimized representation of the group;
• and
• in response to user input, toggling between displaying said open browser window of the first mode, and displaying a plurality of groups of resources in the second mode,
• wherein, in said second mode, each group of resources is:
• minimized to a topmost position in a stack of minimized representations of previously visited groups if said group of resources has not previously been included as one of a plurality of favorite groups of resources;
• and
• minimized to a position in a grid of minimized representations of favorite groups of resources if said group of resources has previously been added to said grid of favorite groups of resources, and
• wherein, in said second mode, a group of resources is added to said grid of favorite groups of resources in response to user input of dragging the minimized representation of said group of resources from the topmost position of said stack to a position in said grid.
