Internet Explorer is the most popular web browser due to its inclusion with Microsoft products since 1995. Firefox is the second most popular due to features like tabbed browsing and spellcheck. Safari is the web browser made by Apple that also has tabbed browsing and bookmark management. Add-ons, plug-ins, Flash, and Silverlight are tools that can be added to browsers to enhance functionality and add things like animations, graphics, and video playback. The first web browser was called the World Wide Web and was created in the late 1980s by Tim Berners-Lee.
