Description
The internet. As it should be. Firefox is a private web browser designed to protect your data, block trackers and make browsing fast, secure and simple. Whether you’re looking for an incognito browser, a private search experience, or a reliable browser for everyday use, Firefox puts you first. Why people choose Firefox: More privacy, less tracking – Firefox automatically blocks social media trackers, cross-site cookies, crypto miners and fingerprinting scripts. Private browsing that protects you – Open private tabs that don’t save your history, searches, or cookies. Lock them with your device security for extra protection. Fewer ads, less clutter – Turn on built-in ad blocking to cut down on distracting ads, leaving more room for what you actually came to see. Fast, smooth performance – Load pages faster by blocking trackers and reducing unnecessary data usage. Get Quick Answers – Ask Firefox a question by voice for a clear answer without digging through search results. Quick page summaries – Shake your phone to cut through long pages and get the key points.
