FillKit for Firefox per Justin Dah-kenangnon

FillKit reads page structure, labels, and surrounding context to detect what each field expects — then fills it with
realistic, coherent data. A checkout form gets a valid card number, matching expiry, and billing address in the same
city. A signup form gets a real-looking name, email, and strong password.

Key features:

• 150+ field types — names, emails, phones, addresses, credit cards, dates, UUIDs, passwords, and more
• 50+ locales — multilingual field detection and locale-appropriate generated data
• Valid & invalid modes — generate correct data or intentionally broken values for edge-case testing
• Keyboard shortcuts — Ctrl+Shift+K to fill all forms, Alt+K for current form, Alt+H to toggle widget
• Fully offline — all processing happens locally, no data leaves your browser
• Zero config — install and start filling. Customize locale, mode, and shortcuts from the options page

Built for developers, QA engineers, and demo environments. All generated data is synthetic — realistic but
entirely fake. FillKit is not intended for filling real forms with real personal information.
