About this app

Take control of your internet with the Firefox browser, wherever you go. Whether you’re looking for an incognito browser, want to use a private search engine, or just need a reliable and fast web browser, Firefox delivers speed, security, and simplicity every time.

Get Firefox so your passwords, browsing history and ad blocker extensions — and the privacy and security you rely on.

What Firefox offers:

✔ A PRIVACY-FOCUSED FAST BROWSER
• Automatic tracker blocking — By default, Firefox blocks trackers and scripts such as social media trackers, cross-site cookie trackers, crypto-miners and fingerprinters.
• Enhanced tracking protection — Choose the “strict” setting as an incognito browser and get even more privacy protections with an ad blocker.
• 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.
• Hide Private Tabs. Private browsing mode can auto-lock when you leave, and require your face, fingerprint, or PIN to unlock.

✔ 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.

✔ PASSWORD MANAGEMENT
• Log into sites easily — Firefox remembers your passwords across devices when you sync to your Mozilla account.
• Firefox suggests passwords for new log-ins and stores them securely.

✔ FAST BROWSER
• Enhanced Tracking Protection automatically blocks ad trackers from following you around the web and slowing down your search engine pages.

✔ TAILORED SEARCH ENGINE OPTIONS
• Get suggestions and previously searched results in the search bar to quickly access the sites you visit most with your browser.
• Move the search bar location from the top to the bottom of the screen, making it easier to navigate with one hand.
• Use the Firefox search widget to search the web directly from your device’s home screen.
• See your recent searches on other devices for seamless searching across mobile, desktop and more.
• Turn on private browser mode to use your choice of private search engine results worry-free.

✔ CUSTOMIZE YOUR FIREFOX EXPERIENCE
• Get helpful add-on extensions, including ad blockers, block certain web pages, turbo-charge privacy settings and more with our private browser.

✔ FIREFOX HOME SCREEN
• Access your recent bookmarks and top sites and see popular articles from across the internet.

✔ SAVE BATTERY WITH DARK MODE
Switch to dark mode on your private browser anytime, reducing eye strain and prolonging your battery power.

✔ WATCH VIDEOS WHILE YOU MULTITASK
• Pop videos out and pin them on top of your screen — or switch to background play and keep the audio going while you multitask. Total control, zero interruptions.

✔ SHARE ANYTHING IN A FEW TAPS
• Share links to web pages or specific items on a page with easy, quick access to your most recently used apps.
• Share securely, whether you’re in private browser or incognito browser mode or not.

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.

Used it for yeaaaaars, but this year Firefox is becoming unworkable. Even when i delete all add-ons, set everything to recommended, i have to turn off the extra security so often to get anything working. Sites become unresponsive, shopping is a mess and firefox focus just deleted my entire shopping card by removing the cookies mid shopping. Your bug report is so complicated it's not even funny. Sorry, but this is not usable.

there is a setting for autoplay, but it's completely pointless, since videos will autoplay, and use sound, even when you select to block both video and sound autoplay. the address bar will auto fill random websites you've never been to(presumably to get paid from them as sponsors). support will completely ignored you, but this review will likely get a response, saying something along the lines of"were looking in to these issues" even though they won't ever look into them.

A nice mobile version of the browser. I do have a few complaints: 1) When opening a private tab, there's an annoying notification asking you to close private tabs and I wish there was some way to get rid of it. 2) I wish you could access the special extension tabs on the homepage. Obviously this is pointless for some but for others it'd be very nice. 3) There's no way to force the Safe Search feature to be at its maximum. As someone who struggles with porn, this would be very useful.
