About Zen Browser

Zen Browser is a free, open-source browser that first appeared in 2024. It is a modified version of Firefox released under the MPL-2.0 license, and its source code is hosted on GitHub in the zen-browser/desktop repository. Its slogan promises "a calmer internet." While keeping Firefox's privacy protections and extension ecosystem, Zen redesigns the interface, moves tabs into a sidebar and adds a range of productivity features. Many of its design ideas resemble those of the Arc browser.

On Windows, Zen's Workspaces feature lets you keep tabs for different projects or topics apart and display only one group at a time, switching between them with a single click. Tabs are arranged vertically in the sidebar, and you can pin tabs within a workspace so the pages you use most are always at hand. The layout is designed for people who keep many tabs open and find a single crowded tab strip hard to manage.

Several other features are aimed at making the most of the screen. Compact mode automatically hides the tab bar and toolbar when you are not using them, leaving as much room as possible for the web page itself. Glance lets you quickly preview a link or a frequently used tab without disrupting the page you are reading. Split view shows two tabs side by side in one window, which is handy when comparing information or working from reference material. For deeper personalization, Zen Mods offers community themes and add-ons that can substantially change the look of the interface.

Because Zen is built on Firefox, it can install Firefox extensions and continues to be updated in step with new Firefox versions. That foundation also means it inherits Firefox's privacy protections rather than relying on a separate engine, so people moving over from Firefox keep familiar extensions while gaining a different way of organizing their browsing.

It is worth noting that the developers still label Zen as being in beta, so individual features may have problems. That makes it best suited to users who enjoy trying new software and like a sidebar layout. If you find the traditional row of tabs across the top of a browser too crowded, Zen is well worth a try.
