KMS U-ONE TV for HTML5 video is an unofficial extension that allows users to watch KMS' U-ONE TV on Chrome for Mac and Linux. This extension replaces the video section with HTML5 video tags, enabling playback on platforms that do not support Flash.

Currently, U-ONE TV can be viewed directly using Flash, so this extension is not necessary for those who already have access to the service. However, for Mac and Linux users who want to watch U-ONE TV on Chrome, this extension provides a solution.

Please note that the developer, nakayuki, created this extension based on a request and may not be familiar with the KMS service itself. This extension is free to use and is categorized under Browsers > Add-ons & Tools.
