User Reviews

Users praise the addon for freeing screen space by hiding UI and for letting you pop out windows and work across multiple monitors. However, Android support is often non-functional or mislabelled, behavior can be unreliable or inconsistent, updates are lacking, and Windows-specific quirks can hamper use. Overall, it’s useful for some setups but unreliable and poorly maintained.

Pros

Space-saving fullscreen that hides toolbars and navigation for a cleaner view.
Supports popping out browser windows and works well on multi-monitor setups.
Popup features and adjustable screen size reduce distractions (single-window viewing).
Works as described for many users and keeps apps in a separate window.

Cons

Android support is non-existent or mislabelled, making it unusable on Android.
Unreliable behavior; sometimes the extension does nothing or fails to exit fullscreen after playback.
Lack of updates/maintenance appears to be a concern; not updated recently according to users.
Windows-specific quirks (e.g., taskbar behavior) can hinder fullscreen usage.

Media Full Screen does not work for auto play. This is not enough for my setup. And I don't know how long this will be updated.

Is Full Screen for Firefox 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.

Full Screen for Firefox requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
