What Firefox offers:
✔ PRIVACY-FOCUSED BROWSING
• 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 and get even more privacy protections.
• Private browsing mode — When you close private mode, your browsing history is automatically erased from your device.
✔ EASY-TO-USE TABS
• Find what you want 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 and vice versa — or choose to keep them separate.
✔ PASSWORD MANAGEMENT
• Log into sites easily — Firefox remembers your passwords across devices.
• Firefox suggests passwords for new log-ins and stores them securely.
✔ LIGHTNING-FAST PAGE LOADS
