Frequently Asked Questions
How do I install the extension for JAV in Incognito mode with one command?
Copy the one-liner command from our Terminal Installer section and run it in PowerShell (Windows) or Terminal (macOS/Linux). It downloads the Private flavor, enables Incognito permissions in your selected profile, injects your License Key, and launches an Incognito window automatically.
Do cached JAV subtitles work across different mirror domains?
Yes. The Private adapter extracts canonical product codes (e.g., SSIS-899, IPZZ-120, JUR-815, FC2-PPV-4512345) from the URL or title, sharing the same subtitle cache across all mirror sites.
Can I choose which Chrome/Brave/Edge profile to install into?
Yes. Run the installer in Interactive Mode to see all detected browser profiles (Default, Profile 1, Profile 2...) with their display names, or pass --profile="Profile 2" directly.
How does it handle non-speech sounds and dialogue context in JAV?
A noise filter drops music and repeated non-speech lines that speech recognition sometimes invents. A per-video content profile, built from the title and the first lines, keeps character relationships and forms of address consistent across the whole movie.
