360 Secure Browser vs Quetta Browser

360 Secure Browser is a free browser available for Android, iOS, Linux, macOS, and Windows. The product describes a Chromium 132 kernel, cross-device sync, and extensions from its own store, which advertises more than 2,000 extensions. Built-in tools include an AI assistant, AI search, AI reading mode, image tools, a PDF reader, and a translation assistant. Login Manager can save and autofill passwords and generate strong passwords. The browser opens image, audio, video, PDF, and text files; extensions can add Office-format support. Its six described protections cover system files and processes, malicious websites and downloads, page sandboxing, crypto-mining scripts, DNS resolution, and isolation of pages, code, plugins, and CPU processes. The homepage also lists encrypted DNS and anti-tracking mode. A separate enterprise product offers centralized configuration, device and client-version management, browser policies, and data controls including watermarks, encrypted on-disk data, screenshot protection, download blocking, access controls, and auditing. Enterprise plans are priced per device: 基础版 is 58 CNY a year beyond 100 free devices, 高级版 is 158 CNY a year, and 旗舰版 is 258 CNY a year.

Quetta Browser is a free Chromium-based browser focused on watching, saving, and managing web video. It is available on Android, iOS, macOS, Windows, and as a desktop extension. For supported sources, it detects MP4, WebM, and HLS/M3U8 media and can offer available download qualities. Playback controls include picture-in-picture, background audio, speed changes, captions, and casting, although availability depends on the video, website, device, and operating system. Built-in ad and tracker blocking works for supported patterns, and Quetta describes blocking matching cross-site tracking requests and known fingerprinting scripts on supported pages. Other tools include reader mode, screenshots, PDF saving, and side-by-side translation. Android supports many Chrome Web Store and Microsoft Edge Add-ons extensions, with compatibility varying. Windows is beta. Quetta does not bypass DRM or other access controls, so some media cannot be downloaded.
