44.9Kstars

Firefox-based browser with vertical tabs, workspaces and split view

Zen Browser is a free, open source browser built on Firefox that brings an Arc-style layout to the Gecko engine: vertical tabs in a sidebar, workspaces, split view, pinned essentials and a compact mode that hides the interface. It works with Firefox add-ons and Firefox Sync, and is developed by a volunteer community for Windows, macOS and Linux.
