User Reviews
Users praise the add-on for reliably maximizing videos into a full-window (not fullscreen), working on many sites and succeeding where others fail. Common complaints are lack of keyboard hotkeys and occasional compatibility problems on some Firefox setups, including reported YouTube auto-maximize issues. Pros
- Reliable and effective — many users report it does what it promises and works where other add-ons fail
- Keeps video in a full-window (not fullscreen) view, useful for multitasking
- Works across a wide variety of websites
Cons
- No keyboard hotkey support — users frequently request hotkeys in addition to the button
- Compatibility issues for some Firefox users; some report the add‑on didn't work for them
- YouTube-specific auto-maximization problems reported by users (may be tied to Firefox/version)

Does not automatically maximize the YouTube video. And ytb.js is not migrated to Firefox.

Is Maximize Video Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Maximize Video requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
Risk impact analysis details
- Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Maximize Video has earned a fairly good reputation and likely can be trusted.
