Firefox's has been reimagined in 2024 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.

Features

A sleek, clean Firefox design backed by research

Going into the Firefox redesign, our team studied how people interact with the browser, observing their patterns and behaviors. We listened to feedback and gathered ideas from regular people who just want to have an easier experience on the web. We obsessed over distractions, extra clicks and wasted time. The resulting new design is simple, modern and fast and delivers a beautiful experience to support what people do most in Firefox.

Streamlined toolbar and menus

The toolbar is naturally where you start every web visit. It's the place where you type a URL to go somewhere online. After web page content, it's what you look at most in Firefox. The new toolbar is simplified and clutter-free so you get to the good stuff effortlessly.

Menus are where key Firefox actions and commands live. We've consolidated extra menus to reduce clutter and be more intuitive through the three bars menu in the upper right or by right-clicking to activate it on your computer screen. The new look reorganized and streamlined our menus to put the best actions quickly at your fingertips.

When privacy protections are engaged in Firefox, the shield icon in the toolbar glows subtly indicating that we're working behind the scenes to protect you from nosy trackers. Fun fact: Firefox has blocked more than 6 trillion --- that's trillion with a T --- trackers since we rolled out enhanced tracking protection, stopping thousands of companies from viewing your online activity.. We're talking about tracking cookies, social media trackers, fingerprinters, cryptominers and more. Go ahead and click on the shield to see who and what Firefox is blocking... you might be surprised by what you find out.

A new look for tabs

Based on our research, we found out that more than half of you have 4+ tabs open all the time, and some of you have more, a lot more. And we feel that! Tab as much as you like, friends. Tabs got a makeover so they are now gently curved and float above the toolbar. It's an exciting change that also serves as a reminder that tabs aren't stationary. So grab those tabs, move them around and organize them as you like. Tabs also got a glow-up to be a touch brighter when active.

Shhhhhh... notifications

No one likes to be interrupted when they're in the flow, but if you must be alerted to something, at least it can look good. We've updated notifications and alerts of all kinds in Firefox to take up less space for less jarring interruptions. Plus, non-essential alerts and messages have been removed altogether. Media autoplay is turned off by default, so you won't be interrupted by a random video blasting unexpectedly. Spotting a noisy tab is easy, and unmuting/muting takes just a quick click on the tab itself.

Expanded privacy protections

Mozilla makes it our mission to put your privacy and security first in the technology we develop. Our goal is for you to worry less every time you go online. The latest Firefox release comes to you with next-level security and privacy that you've come to expect from us.

The best private browsing mode out there

All browsers have a private browsing mode, but none match Firefox. The popular Total Cookie Protection moves from the optional strict setting to always-on in private browsing. This feature maintains a separate "cookie jar" for each website you visit while browsing privately. Any time a site deposits a cookie, Firefox locks it up in its own cookie jar so that it can't be shared with any other website.

An even better Firefox for iOS and Android

The fresh new look covers Firefox everywhere, from desktop browsers to Android and iOS mobile devices. The iOS experience is optimized for iPhone and iPad, with key actions now taking fewer steps for quicker searches, navigation and tab viewing. With refinements in iconography and menu names, the whole browsing experience is more cohesive and harmonious across every platform.

Shape Up Your Floats

CSS Shapes lets a floated element sculpt the flow of content around it beyond the classic rectangular bounding box we've been constrained to. For instance, in the above screenshot and linked demo, the text is wrapping to the shape of the grapes vs the image's border. There are properties for basic shapes all the way up to complex polygons.

You can learn more in Josh Marinacci's post on the new CSS Shapes tooling from yesterday.

Variable Fonts Are Here

No punny title, I'm just excited! OpenType Font Variations allow a single font file to contain multiple instances of the same font, encoding the differences between instances. In addition to being in one file, font creators can expose any number of variation axes that give developers fine-grained control on how a font is rendered. These can be standard variations like font weight (font weight 536 looks right? no problem!) or things that were never previously available via CSS (x-height! serif-size!). In addition to the candy-store possibilities for typography nerds, being able to serve a single file with multiple variants is a major page weight savings. Dan Callahan goes much deeper on the grooviness to be found and how Firefox makes it easy to tweak these new custom values.

What's New

New

  • Firefox now displays images and descriptions for search suggestions when provided by the search engine.
  • The translations feature received an improvement in the quality of translated webpages. The results should be much more stable. This fixes issues where the content of a page could disappear when translated, or interactive widgets could break.
  • Firefox now supports creating and using passkeys stored in the iCloud Keychain on macOS.
  • MDN Web Docs article suggestions from Firefox Suggest will be available in the address bar for users searching for web development-related information.
  • The line breaking rules of Web content now match the Unicode Standard. This improves Web Browser compatibility for line breaking. An additional improvement for East Asian and South East Asian end users, Firefox now supports proper language-aware word selection when double-clicking on text for languages including Chinese, Japanese, Burmese, Lao, Khmer, and Thai.
  • Firefox now ships with a new .deb package for Linux users on Ubuntu, Debian, and Linux Mint.

Fixed

  • Various security fixes.

Enterprise

  • You can find information about policy updates and enterprise specific bug fixes in the Firefox for Enterprise 122 Release Notes.

Developer

  • Fixing keyboard navigation in Inspector Rules view. Starting with Firefox 122, when editing a selector, a property name, or a property value in the Inspector, the Enter key will no longer move the focus to the next input but will validate what was entered and focus the matching element (#1861674). You can still use Ctrl + Enter (Cmd + Enter on macOS) or Tab to validate and move the focus to the next input.

Web Platform

  • Enabled the offset-position property which is useful for most of the offset-path values. Added support for ray(), basic-shape, coord-box to the offset-path CSS property. Added support for rect() and xywh() basic shapes on clip-path and offset-path CSS properties.
  • Firefox now supports animating the SVG viewBox attribute using SMIL by animations.
  • by animations are animations that are relative to the original value. Other attributes such as lengths and angles already support by, but a viewBox consists of four separate values.
  • The LargestContentfulPaint API has been added, this provides timing information about the largest image or text paint before users interact with a web page.
  • hr in select is now supported, allowing websites to easily use separators inside a select element.
