We’ve always had your back on privacy, and still do.

Firefox is considered a secure and private web client.

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.

Is Firefox better than Google Chrome?

Firefox andChromeare updated every few weeks, so it’s hard to compare them over time.

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?

In fact, Firefox is one of the last major browsers that isn’t.

Firefox runs on its own Quantum surfing app engine.

We obsessed over distractions, extra clicks and wasted time.

Streamlined toolbar and menus

The toolbar is naturally where you start every web visit.

It’s the place where you key in 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.

The new look reorganized and streamlined our menus to put the best actions quickly at your fingertips.

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.

Plus, non-essential alerts and messages have been removed altogether.

Spotting a noisy tab is easy, and unmuting/muting takes just a quick punch the tab itself.

Our goal is for you to worry less every time you go online.

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.

There are properties for basic shapes all the way up to complex polygons.
