In their own words
Maxthon
Maxthon is a free Chromium-based browser with built-in notes, password management and an AI chat assistant. Signing in syncs bookmarks, settings, Maxnote, password-manager data and quick-access URLs across devices. Maxnote can record, organize, clip and share URLs, text, images and links. Maxthon 7 supports Chrome extensions, and its desktop versions can sync extensions between Windows and macOS. Reading mode removes ads and other page elements, Read Aloud converts webpages to speech, and split-screen browsing shows multiple pages in one window. Listed privacy tools include ad blocking, anti-tracking, incognito mode and a free VPN provided by Bright Data. Maxthon's privacy policy says searches through its default MaxAsk engine, which uses Google as its search content provider, involve collecting search queries, IP addresses and browser details. Maxthon says it encrypts account information and sensitive data stored locally or in the cloud, as well as data during account synchronization. Super Bookmarks requires a VIP subscription, and video downloads are limited for logged-in users.
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.
