Browser tabs provide a convenient way to open multiple sites at once, but many users find them accumulating to the point of becoming overwhelming. Toby is a tab management extension designed to tame large sets of tabs, even making tabs suitable as a replacement for bookmarks. Users can create any number of named collections of tabs. Within a collection, users may also apply tags (e.g., todo, clients, projects, etc.) to individual tabs. Toby allows users to create up to eight tags. Users may also create organizations to contain collections. By using an optional Toby account, users may share these organizations with other users. Toby is available for Google Chrome and Mozilla Firefox. Opera users can also use Toby through the "Install Chrome Extensions" Opera plugin.
