User reviews
Users appreciated the extension for enhancing YouTube's viewing experience with windowed fullscreen mode and simple functionality. However, recent monetization changes—locking core features behind a paywall and requiring login and additional permissions—have caused widespread dissatisfaction. Users report bugs needing frequent page reloads, intrusive ads for premium, and performance issues. The lack of transparent pricing and aggressive monetization alienate many long-term users, who are turning to free alternatives. While the extension remains useful when functional, the combination of paywalls and reliability problems overshadow its original benefits.
Pros
- Provides a windowed fullscreen mode for YouTube, improving the viewing experience beyond the default theater mode.
- Was reliable and effective in its core functionality before recent changes.
- Simple and easy to use when functioning correctly.
- Some users find the display superior to YouTube's theater mode.
- The extension has a clean, minimal interface without major fuss when working.
Cons
- Recent updates have moved previously free core features, especially auto fullscreen, behind a paywall.
- The extension often requires frequent page reloads to get the fullscreen button to appear and work properly.
- It now requires additional permissions and login, sometimes for non-essential features, which concerns users.
- Performance issues such as the extension failing to load or becoming unreliable after updates.
- Lack of transparent pricing and confusing monetization model, causing frustration among users.
- Advertisement for premium features appears frequently, annoying users.
- The developer's approach to monetization is seen as aggressive, driving users to seek alternatives.
Recent reviews
Monetization features have begun to creep in and thus enshittification is in full steam, including paid promotion overlays and locking previously free features behind a paywall - the extension also just started to require permissions for notifications, which are DEFINITELY NOT REQUIRED for the core functionality. Uninstalling right now.

Olavi Varis, 2025-03-20I'll eat a bag of big ones before I pay for a glorified CSS edit
Word to the wise, there are free and less bloated solutions that don't paywall things like scrolling lol
Edit: I appreciate the response, but your payment model is really silly. I'm hugely pro-donationware and not at all upset about the price. But the blunt truth is that you turned some of the free features into paid features requiring a login lol
There are other free options that are just as reliable, sorry.
You're right that one star was unfair, I have adjusted it to three as I did use it for months as a free user.
