Description

Primes in a range, password generator, and browser fingerprint. Offline popup only. Prime Numbers is a compact popup for everyday developer tasks and more. What's inside - Prime numbers — enter a range (up to 50,000 numbers) and get a list of primes; click a value to copy it. - Password generator — random passwords at your chosen length (8–32), with options for character sets (uppercase, digits, symbols); click a row to copy. - Fingerprint — local browser fingerprint via bundled FingerprintJS: visitor ID, confidence, user agent, component signals, and canvas preview; fields and JSON are copyable on click. Privacy Nothing is sent to remote servers. Fingerprinting runs entirely in the extension popup on your device — no network requests, no host permissions.
