  • Does Firefox sell your personal data?

    Nope. Never have, never will. And we protect you from many of the advertisers who do. Firefox products are designed to protect your privacy. That’s a promise.

  • Why is Firefox so slow?

    Firefox isn’t slow… now. In 2017, we completely rebuilt our browser engine (called Quantum), to ensure Firefox could compete with other major browsers. And, our tracker blockers help pages load even faster. So Firefox is lightning fast without sacrificing any of your privacy.

  • Is Firefox Chromium based?

    Firefox is not based on Chromium (the open source browser project at the core of Google Chrome). In fact, we’re one of the last major browsers that isn’t. Firefox runs on our Quantum browser engine built specifically for Firefox, so we can ensure your data is handled respectfully and kept private.

  • Does Firefox use Google?

    Google is the default search engine in Firefox, which means you can search the web directly from the address bar. Learn more about search engine preferences and changing defaults.

  • Does Firefox have a built-in VPN?

    Firefox does not have a built-in VPN (virtual private network), but there are two products made by Mozilla/Firefox that you can use in addition to the private Firefox Browser that can protect either your browser (Firefox Private Network) or device (Mozilla VPN) connection on WiFi, as well as your IP address.
