Non-limiting examples of the present disclosure describe processing via an extension of a web browser application. A processing device, for example, may provide a web browser application that comprises an extension enabling an application service to interface with the web browser application. Input may be received in a uniform resource locator (URL) bar of the web browser application. A search of an application service may be launched directly from the URL bar based on the received input. The processing device may retrieve results from the application based on the searching. The retrieved results may be displayed within the URL bar on a display connected with the processing device. Other examples are also described.
