DuckDuckGo Browser vs Mozilla Firefox

DuckDuckGo Browser is a browser for Android, iOS, macOS, and Windows, with a free plan and paid subscriptions. It blocks third-party trackers, including those from Facebook and Google, and most ads, including video and YouTube ads. It can block most cookie pop-ups and may opt users out automatically. Cross-device sync and a password manager are included, and a one-click control clears tabs, history, and browsing data. Email protection blocks hidden trackers in emails, while Duck.ai offers optional private chats with popular AI models. DuckDuckGo says those conversations are not used to train AI and that it does not track searches; its tracker list and exceptions are open source. Paid plans add VPN protection, advanced AI models, personal information removal, and identity restoration. Plus costs $9.99 a month or $99.99 a year. Pro costs $19.99 a month or $199.99 a year and adds Claude Opus 4.8, GPT-5.6 Sol, higher reasoning effort, and twice Plus’s Duck.ai usage limits. DuckDuckGo has been independent since its founding in 2008 and is based in Paoli, Pennsylvania.

Mozilla Firefox is a free, open-source web browser that uses the Gecko engine. It is available on Windows, macOS, Linux, iOS, Android, and as a browser extension, and its download page lists availability in more than 90 languages. Standard tracking protection and built-in ad blocking are included. Total Cookie Protection isolates cookies so they cannot follow users between websites, while Tab Groups organize open tabs by project, mood, or task. A Mozilla account can sync bookmarks, passwords, and open tabs across devices. Firefox also offers access to multiple AI chatbots in one place, letting users choose whether to use them. Thousands of free extensions are available through addons.mozilla.org. Mozilla’s privacy notice says browsing history, form data, temporary files, and cookies are processed on the device unless stated otherwise. Automated translation and PDF alt-text suggestions use downloaded language models locally; Firefox says those features do not send page content, PDFs, images, or tab URLs to Mozilla. Firefox is listed at free.
