Maintains fullscreen mode for specific domains across redirects. # Sticky Fullscreen This Chrome extension maintains fullscreen mode for specific domains across redirects. ## The Problem Some web applications, especially those used for presentations or dashboards, are best used in fullscreen. However, when you navigate or are redirected to a new page within the same domain, the browser often exits fullscreen mode. This can be disruptive and require manual intervention. ## The Solution Sticky Fullscreen allows you to whitelist specific domains where you want to enforce fullscreen mode. Once a domain is on the list, the extension will ensure that any tab navigating to that domain automatically enters fullscreen. ## How it Works The extension listens for navigations. When a tab finishes loading, the extension checks if the URL belongs to a domain on your whitelist. If it does, it will try to make the window fullscreen. There are user-controllable options (see below) to tweak when and how the extension shows its overlay and triggers fullscreen. ## Arc browser compatibility Some Chromium-based browsers (notably Arc) block extensions from forcing fullscreen programmatically because fullscreen entry typically requires a user gesture. When that happens the extension cannot silently set the window to fullscreen. This extension includes a fallback for browsers that block programmatic fullscreen: it attempts `chrome.windows.update({ state: 'fullscreen' })`, and if that fails the content script shows a small overlay button on matching pages. Clicking that button runs the page's `requestFullscreen()` call — a user gesture — which will enter fullscreen in browsers that block programmatic fullscreen. Known behavior: - Google Chrome (standard builds): the extension can usually set the window to fullscreen automatically. - Arc and other Chromium forks: programmatic fullscreen may be blocked; the overlay button provides a one-click workaround. ## How to Use 1. Click the extension icon in your browser toolbar. 3. Enter the domains you want to keep in fullscreen, one per line. For example: ``` example.com app.another-domain.net ``` 4. Click "Save". 5. Visit a whitelisted site and use the new options: - Show Fullscreen Button: toggles the overlay button (it auto-hides after 10 seconds). - Avoid fullscreen on initial page load: when enabled, the extension will skip attempting fullscreen on the first completed navigation for a tab and will only act after a later redirect/navigation. - Hide Mouse Cursor: when enabled, hides the cursor after 10 seconds of inactivity on allowed sites. Note: the overlay hide timeout is now hardcoded to 10 seconds. ## For Developers The background script (`background.js`) contains the core logic. It uses the `webNavigation` and `chrome.windows.update` APIs to detect navigation and attempt fullscreen. For browsers that block programmatic fullscreen, a content script (`content.js`) shows a clickable overlay that calls `document.documentElement.requestFullscreen()` as a user gesture.

If you change the "Avoid fullscreen on initial page load" option, try reloading the extension and performing a redirect or navigation within the same tab to verify the behavior. Version: 1.2.0
