Firefox’s has been reimagined in 2025 to be fast, modern and inviting the first time you run it and every day after. We’ve always had your back on privacy, and still do. We think the browser should be a piece of software you can rely on to have your back, pleasant to look at and working seamlessly with the web.

Is Firefox a trustworthy browser?

Firefox is considered a secure and private browser. By default, Firefox blocks known third party trackers, social media trackers, cryptomining scripts and fingerprinters from collecting your data.

Does Firefox use Google as a search engine?

Yes, Google pays hefty royalties to Mozilla/Firefox for making them the default search engine in Firefox. That deal is worth around $400 million per year (as of 2021-2022) and makes up the vast majority of Mozilla’s total revenue.

Is Firefox better than Google Chrome?

Firefox and Chrome are updated every few weeks, so it’s hard to compare them over time. At one point, Firefox has offered advantages over Chrome in terms of RAM usage, but that claim can go back and forth depending on the revision (and the potential for regressions). Microsoft Edge and Apple’s Safari have also made such claims, but in general all browsers are continually improving and beating each other.

Firefox does offer better privacy and customizability (to an extent) and is a solid browser with lots of add-ons available. If you want the best customizability on a stock browser, you should also check out Vivaldi (Chromium based).

Who owns Firefox?

Firefox is developed by the Mozilla Foundation, a US-based non-profit that operates and controls the Mozilla project.

Is Firefox based on Chromium?

No, Firefox is not based on Chromium. In fact, Firefox is one of the last major browsers that isn’t. Firefox runs on its own Quantum browser engine.
