Firefox is a fast, private web browser designed to protect you by default. Privacy is built in from the start, so you can focus on what matters instead of worrying about who’s watching. Why people choose Firefox: • Enhanced Tracking Protection – Blocks trackers by default to help stop companies from following you across the web. • Private browsing mode – Browse without saving your history, searches, or cookies. • Page summaries – Get the key points from long pages and move on faster. • Built-in password manager – Generate strong passwords, save them securely, and autofill logins when you need them. • Flexible search options – Choose your default search engine or switch search engines right from the search bar. • Reader Mode – Remove ads and clutter from articles so you can focus on what you’re reading. • Sync across devices – Pick up where you left off with synced tabs, bookmarks, and passwords when you sign in to your Mozilla account. Private by default Firefox is designed with privacy built in from the moment you start browsing. Enhanced Tracking Protection automatically blocks common background trackers, including social media trackers, crypto miners, and fingerprinters. When you want extra privacy, private browsing mode doesn’t save your history, searches, or cookies. Focus on what matters The web can be distracting. Firefox is designed to help you stay focused without making you manage everything yourself. Reader Mode clears clutter from articles, and picture-in-picture keeps videos visible while you multitask—without pulling focus from what you’re doing. Browse your way Customize Firefox to fit how you browse. Personalize your home screen with wallpapers and layout options, and choose your preferred search engine instead of being pushed into a single ecosystem. You can move the search bar to the top or bottom of the screen for easier one-handed browsing. Sign in to your Mozilla account to sync tabs, bookmarks, passwords, and browsing history across devices, so switching feels seamless. Built for people, not profit Firefox was created in 2004 by Mozilla as a faster, more private, and more customizable alternative to other browsers. Today, Mozilla remains a nonprofit and continues working to make the internet — and the time you spend on it — better.

It’s the browser I reach for when I want to browse confidently without feeling like I’m losing control of my data. The app opens quickly, and the interface is clean and uncluttered, letting the content take the spotlight. I appreciate how smoothly it syncs with my other devices when I’m signed in, so I can pick up right where I left off—whether that’s a tab I left open on my laptop or a password I saved earlier. Privacy is where Firefox shines. Enhanced Tracking Protection is effective without making pages feel broken, and Total Cookie Protection helps keep third-party trackers at bay without me having to think about it. It’s reassuring to know there are solid privacy defaults baked in, and the settings to fine-tune things are straightforward rather than overwhelming. As someone who spends a lot of time reading articles and debugging web pages, the built-in tools are genuinely useful. The Reader Mode makes long reads less taxing on the eyes, and the overall performance feels snappy, even with multiple tabs open. I also value the open-source ethos behind Firefox; it’s comforting to know there’s a transparent, continuously improving foundation behind the product. If you value privacy without sacrificing ease of use, Firefox on iOS is a strong choice. It respects your autonomy, plays nicely with other devices, and delivers a smooth, human-centric browsing experience. Also, the sending pages to named devices is TEH BOMB!!!

The best and safest browser 11/01/2022 Systems Analyst 1/2 Century I was a computer scientist, systems analyst and support technician for 51 years. I am also a woman. I have exclusively used Firefox since it’s inception. I have always been impressed that it is nonprofit. In 2013, I had 2 PC’s and my bank card. Having hacked the stolen computers, the perp was able to access my bank account and steal $300,000. She was able to gain remote access to my other computers and commit other crimes. I was able to track her activities, but law enforcement did nothing, because they didn’t believe a woman could know that much about computers and the law. Using Firefox, I was able to protect myself from this known hacker. Any time she broke through Firefox’s secure settings, if Firefox didn’t first notify me, I would notify them, and my accounts would again be sufficiently secured. The techs at Internet Explorer or Chrome wouldn’t have done the same. I am forever grateful to the people who have made Firefox possible. I love Nightly. Not only will I always exclusively use Firefox, I have promoted it to all of my clients, and anyone else who would listen because they cared about safety when on the Web. I will continue to do so because I have faith and experience that no other browser can even come close to what Firefox can do.

Please make an option to enlarge the font! 01/06/2023 gdgrl666 I have an autoimmune disease that is destroying my eyes and sadly I am not going to be able to use Firefox on my mobile much longer which makes me very sad because I find it to be the safest browser I've ever used. Sure there are some other things that could be improved but hey it's all a work in progress! I did see on the website where other people have wanted or looked for an option to be able to to this the
