In their own words
Mozilla Firefox
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.
Samsung Internet
Samsung Internet is a free web browser from Samsung for Android phones and tablets, Windows PCs, and browser extensions. It uses the Chromium engine and supports continuing browsing between devices. That handoff requires the same Samsung Account on both devices; continuing apps also requires Wi‑Fi, Bluetooth, and the “Continue apps on other devices” setting. Galaxy AI features can summarize or translate webpages and read selected text aloud on supported devices. Availability depends on language, region, operating system, and device, and some features may require a network connection and Samsung Account. Users can move the menu and URL bar, rearrange the Customize menu, and add up to seven toolbar features. Secret Mode removes cookies and browsing history after its tabs close, while saved items remain available only there. Samsung Internet includes Smart Anti-Tracking, a Privacy Dashboard, biometric sign-in on supported devices, and video playback controls. PC content blockers are supported; Android ad blocking requires a compatible third-party app.
