Usage: 1. Click on toolbar button 2. Select video that you want to maximize (you can click toolbar button again to cancel) NOTE !!!!!! 1. This extension only maximize video, it can't remove web advertisements for you. If you need remove web advertisements, you can install other extension to do that. 2. No promise to support EVERY video site. If it can't work on specific web site, report to me: https://github.com/ettoolong/MaximizeVideo/issues I will try to fix it ( if I can).
