Remove visual clutter and maximizes videos for easy viewing, including full-page theater mode on most sites.

WHAT IT DOES: Universal Video Maximizer is a free and open source Chrome extension that allows users to watch videos in full-browser-window mode on most websites, without the extension requiring full permissions to every site. It also has a "theater mode" that removes the navigation bar and other UI elements for a undistracted viewing experience. ✔ Working great since 2013 ✔ Dark themed theater mode ✔ Secure and private! ✔ Great for ultrawide monitors ✔ Free and open source ✔ Control playback speed on most sites (Prime, HBO, Apple, etc) This extension is FREE and done as a hobby.

I would say 5 stars except it cant play the next video in a playlist on youtube, you have to manually exit it, and click the next video, then re-enter max size. It'd be nice if it automatically went to next video and entered full screen again. Maximize video does this, except it doesnt work on this pc.

I had to come back and give this extension 5/5, it was exactly what I needed and use it everyday with no issues.
