Stay Ahead of Data Breaches with Lockwise

In the event of an online data breach, Firefox Lockwise alerts you to potentially vulnerable passwords, allowing you to update them and maintain your privacy. This innovative feature gives you peace of mind, knowing that your sensitive information is protected.

Generate Complex Passwords with Ease

Creating strong, unique passwords has never been easier. Firefox 70 introduces a new feature that generates complex passwords when you create a new online account. These passwords can be stored in Firefox Lockwise, ensuring that your online accounts remain secure.

Experience Lightning-Fast JavaScript Performance

The new Baseline Interpreter in Firefox 70 takes JavaScript performance to the next level. By executing bytecode in a fixed interpreter loop and utilizing inline caches, this feature improves performance, reduces memory usage, and enhances page load speed.

// Example of improved JavaScript performance
function fibonacci(n) {
  if (n <= 1) return n;
  return fibonacci(n - 1) + fibonacci(n - 2);
}
console.log(fibonacci(40)); // Output: 102334155
