• Customize your search engine — Set your favorite private search engine as the default for convenient browsing.
• Ad blocker extensions — choose your favorite ad blocker extension to eliminate unwanted pop-ups and ads.
• Private browser mode — Search in a private tab, and your browsing history is automatically deleted from your device when you close Firefox.
✔ EASY-TO-USE TABS
• Find what you want with your search engine quickly — create as many tabs as you like without losing track.
• See your open tabs as thumbnails or a list view.
• See tabs from your phone on your desktop web browser and vice versa when you sync to your Mozilla account.

BILLIONAIRE FREE FOR 20+ YEARS
The Firefox browser was created in 2004 by Mozilla as a faster, more private browser with more customizable features than web browsers like Internet Explorer. Today, we are still not-for-profit, still not owned by any billionaires and still working to make the internet — and the time you spend on it — better.
