Presenting a web application includes receiving a user's selection of a UI element, which includes a visual icon representing the web application. In response to receiving the selection, the web application is launched in a browser window, where the browser is customizable to store bookmarks to webpages, and the browser can display multiple tabs of different webpages in a browser window. The browser window in which the web application is launched is tabless and includes chrome displaying back and forward buttons, where the buttons are selectable to navigate to a webpage in a history of webpages viewed by the user, and a reload button that is selectable to reload a webpage currently-viewed in the window. The chrome includes no UI elements that may be selected to store a bookmark to a webpage and includes no UI elements that display user-defined bookmarks to webpages.
