Features & Capabilities

Auto Fullscreen is a simple Firefox extension designed to automatically open all browser windows in fullscreen mode, including those opened after the initial launch. Unlike the original Auto Fullscreen add-on which only makes the initial window fullscreen, this fork ensures every window, even those created when opening tabs in separate windows, adopts fullscreen. This is perfect for users who prefer an immersive browsing experience across multiple windows. Additionally, users seeking to view bookmarks in fullscreen mode can follow provided guidelines (handling at your own risk). For bug reports or feature requests, contributions can be made via its GitHub issues page.

User Reviews

Users praise the add-on for reliably enabling automatic fullscreen across platforms (Linux and Windows) and for working especially well when combined with full-screen-api.ignore-widgets. Multiple reviewers requested additional features or fixes: bookmarks toolbar compatibility, per-site control, and a taskbar auto-show behavior in fullscreen.

Pros

Reliable and does what it promises—multiple users report it solved their fullscreen issues
Cross-platform: users report it works on Linux and Windows
Works especially well when used with the full-screen-api.ignore-widgets setting for a borderless/PWA experience

Cons

Missing some UI/feature integrations reported by several users (requests include making the Windows taskbar appear on hover in fullscreen)
Bookmarks toolbar incompatibility reported by users
No per-site control option (users requested the ability to limit fullscreen to specific sites)

Is Auto Fullscreen 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.

Auto Fullscreen does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

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.

Auto Fullscreen has earned a fairly good reputation and likely can be trusted.
