Methods and systems are provided for managing a GUI of a web browser. When a user interaction with a tab presentation control is detected, a horizontal tab strip having first navigation tab controls for a set of webpages is removed, and a vertical tab strip having second navigation tab controls for the same set of webpages is displayed in a vertical column in the browser. In response to detecting a user hover interaction with the vertical tab strip while the vertical tab strip is in a collapsed state, the vertical tab strip is expanded from the collapsed state to an expanded state. In response to termination of the user hover interaction, the vertical tab strip is collapsed from the expanded state to the collapsed state. The vertical tab strip in the collapsed state occupies a smaller portion of the GUI then the vertical tab strip in the expanded state.
