Features & Capabilities

ForceFull is a minimalist Firefox extension designed to enhance your browsing experience by automatically maximizing the browser window and switching it to fullscreen mode upon program startup. It allows users to enjoy a distraction-free environment immediately when launching Firefox. To exit fullscreen, simply press F11 or disable the extension if you prefer not to use fullscreen mode.

Please note that ForceFull only operates on the initial Firefox window at startup and does not affect any additional windows opened later. This behavior might impact setups involving multiple screens, as only the primary window is maximized and fullscreened.

User Reviews

Users generally find ForceFull effective in automatically launching Firefox in full screen, aiding in convenience and protecting displays from burn-in. It is praised for simplicity and smooth performance, especially in kiosk setups. However, some encounter issues such as full screen applying only to one tab, the add-on being hard to locate or non-functional in certain Firefox versions, indicating occasional compatibility problems.

Pros

Effectively enables full screen on startup without manual intervention like pressing F11.
Helps prevent screen burn-in on displays by starting Firefox in full screen mode.
Works well for kiosk setups and reduces full screen lag.
Simple to use and performs as promised without needing additional scripts.

Cons

In some cases, the add-on only goes full screen in one of multiple tabs, not all.
Some users report that the add-on does not activate full screen and is not visible in Firefox customization UI.
Compatibility issues with certain Firefox versions have been noted (e.g., FF 58.0.2/64Bit).

Recent reviews

Good addon, but when it opens in my two tabs it goes full screen in only one.

Is ForceFull 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.

ForceFull 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.

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