Sticky Fullscreen is a Chrome extension designed to maintain fullscreen mode on specific domains, preventing users from being redirected back to windowed mode during navigation. This utility is particularly beneficial for web applications, monitoring dashboards, and presentation tools that thrive in fullscreen. Users can easily whitelist domains to ensure uninterrupted viewing, making it a valuable tool for IT operations, digital signage, and kiosk modes.

One of the standout features is the smart fallback option, which provides a one-click button for browsers that may block automatic fullscreen transitions, such as Arc or certain Chromium builds. Sticky Fullscreen requires minimal permissions and ensures that no data leaves the user's browser, making it a lightweight and secure addition to any Chrome setup.
