A site-specific browser (SSB) is a software application that is dedicated to accessing pages from a single source (site) on a computer network such as the Internet or a private intranet. SSBs typically simplify the more complex functions of a web browser by excluding the menus, toolbars and browser chrome associated with functions that are external to the workings of a single site. These applications can be started by using mostly a desktop icon using the favicon.
Site-specific browsers are often implemented through the use of existing application frameworks such as Gecko, WebKit, Microsoft's Internet Explorer (the underlying layout engines, specifically Trident and JScript) and Opera's Presto. SSBs built upon these frameworks allow web applications and social networking tools to start with desktop icons launching in a manner similar to standard non-browser applications. Some technologies, including Adobe's AIR and JavaFX use specialized development kits that can create cross-platform SSBs. Since version 6.0, the Curl platform has offered detached applets and the EmbeddedBrowserGraphic class which can be used as an SSB on the desktop.
