## Description

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.

## Review summary

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).
