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.
Yandex Browser
Yandex Browser is a free Chromium-based browser for Android, iOS, Linux, macOS, and Windows. It can import data and settings from another browser, organize tabs into groups, and sync passwords, bookmarks, history, tabs, extensions, and settings across devices with a Yandex ID. Built-in tools translate text, image captions, websites, documents, and videos; YandexGPT-powered features support editing, summarizing, translation, text-to-speech, and creative processing. The browser can summarize YouTube videos, articles, and text, and provide timestamps for video highlights. Protect can block dangerous or fraudulent pages and help secure passwords and card data; password checks flag simple, reused, or publicly exposed passwords. Users can identify trackers and block those they do not trust, and install extensions from the Chrome and Opera catalogs. Yandex says some data is sent to its servers for technical tasks and usage statistics. Download scanning is available only on Windows, and the maker says browser protection is not a full antivirus product. Sync works across Yandex Browser, not between different browsers.
