Mediabox is a free Chrome add-on developed by dflorent.pokap. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. The purpose of Mediabox is to provide users with a simple popup where they can store videos to watch without interrupting their navigation.

With Mediabox, users have the ability to "up" their video by adding it to a list. This list can then be accessed to view the videos, allowing users to watch them again either within the list or in a separate popup. Currently, Mediabox supports popular video platforms such as Youtube, Dailymotion, and Vimeo.

Mediabox provides a convenient solution for users who frequently come across videos while browsing the internet and want to save them for later viewing. By offering a popup interface and support for multiple video platforms, Mediabox enhances the video-watching experience without disrupting the user's browsing activities.
