Blocks native fullscreen transitions while emulating a true fullscreen state to websites, and suppresses tab-switch / visibility detection.
Blocks native fullscreen transitions while emulating a true fullscreen state to websites, and suppresses tab-switch / visibility detection. Useful when you want pages to behave as if they’re in fullscreen or focused without actually switching window mode.
Prevents sites from forcing an actual fullscreen change (or showing intrusive fullscreen overlays) while still allowing site scripts to behave as if fullscreen is active.
Stops basic tab-switch detection so pages continue playback or tracking behavior that would otherwise pause/stop when you switch tabs.
Some sites use additional signals (screen/window size checks, pointer lock, media APIs, timing differences) and may still detect spoofing. This script targets the most common JS-based checks but is not guaranteed to be undetectable.
Sites that rely on real native fullscreen for functionality (e.g., pointer lock, some DRM flows) may not work correctly.
Do not use this script to violate a site’s terms of service or to commit fraud. Respect content provider rules and local laws. The author is not responsible for misuse.
