FAST. SMART. YOURS.
Firefox is made with you in mind and gives you the power to take back control of your Web experience.
That’s why we design the product with smart features that take the guesswork out of browsing.
SEARCH INTELLIGENTLY & GET THERE FASTER
- Firefox anticipates your needs and intuitively provides multiple suggested and previously searched results across your favorite search engines. Every time.
- Easily access shortcuts to search providers including Wikipedia, Twitter and Amazon.
NEXT LEVEL PRIVACY

SYNC FIREFOX ACROSS YOUR DEVICES
- With a Firefox Account, access your history, bookmarks and open tabs from your desktop on your smartphone and tablet.
- Firefox also safely remembers your passwords across devices so you don’t have to.
INTUITIVE VISUAL TABS
- Intuitive visual and numbered tabs easily let you find content for future reference.
- Open as many tabs as you like without losing track of your open Web pages.
EASY ACCESS TO YOUR TOP SITES
- Spend your time reading your favorites sites instead of looking for them.
ADD-ONS FOR EVERYTHING
- Take control of your Web experience by personalizing Firefox with add-ons like ad blockers, password and download managers and more.
