Zen Browser Function Introduction
Zen Browser is a fork of Mozilla Firefox designed to deliver a cleaner, more focused browsing experience while preserving the extension compatibility and security benefits of the underlying Gecko engine. It introduces features like side-bar tab management, split view (tiling tabs within one window), workspace containers, Glance (preview popups), a rich theming/mod system (Zen Mods), and a compact mode to reduce interface distractions.

FAQ (Common Questions)
Q: Does Zen Browser support Chrome/Chromium extensions?
A: No — Zen is based on Gecko, so it supports Firefox (WebExtension) extensions, not Chrome’s extension ecosystem.
Q: Can I stream Netflix or other DRM content?
A: DRM support is limited; some users report failures with Widevine-protected content. It may not reliably work for all streaming services.
Q: Will my Firefox profile or data import?
A: Yes — Zen can import bookmarks, history, passwords, and extensions from your Firefox profile during setup.
Q: How frequent are updates?
A: Very frequent. The dev team publishes detailed changelogs (e.g. v1.16.2b) containing UI tweaks, bug fixes, and performance improvements.
Q: Is it stable enough for daily use?
A: For many users yes — though occasional bugs or crashes may arise during heavy multitasking. But crash recovery is robust and data is well preserved.
Q: Is there mobile/Android or iOS support?
A: Currently, there is no official Zen Android/iOS client. Many users sync data via Firefox mobile and use Firefox for mobile browsing.
