About Zen Browser

Zen Browser is a free and open-source web browser introduced in 2024. It is a fork of Firefox released under the MPL-2.0 license and developed on GitHub, with a focus on privacy, customizability and design. Many of its layout ideas resemble those of the Arc browser.

On Windows, Zen moves tabs into a sidebar and adds Workspaces to separate projects, Compact Mode to hide the toolbars when not needed, Glance for quick previews and Split View for viewing two tabs side by side. Zen Mods let users customize the look, and Firefox add-ons are supported. The project is still labeled beta.

Key features

  • Workspaces for grouping tabs
  • Compact Mode hides toolbars
  • Glance quick previews
  • Split View for two tabs side by side
  • Vertical sidebar tabs
  • Zen Mods customization
  • Firefox add-on support

Antivirus blocks it

Open-source apps are often flagged because they aren’t commercially signed. Check the SHA256 first, then allow it in your antivirus.

Won’t start, or a DLL is missing

Usually a missing runtime. Install Microsoft’s Visual C++ Redistributable (x64) and the .NET Desktop Runtime, then try again.
