Zen Mode — Zen Mode Dev

Zen Mode turns cluttered webpages into a clean, customizable reading experience designed to help you focus on the content that matters.

Open an article and activate Zen Mode to remove distracting navigation, sidebars, ads, popups, and other page clutter. Read in a clean full-page view or use Split View to keep the original webpage and distraction-free article visible side by side.

Images & Links — Your Choice

Zen Mode starts with a minimal reading experience, but you can choose to display article images and links whenever you need them. Images and links can be controlled independently from Settings.

Privacy-first

Zen Mode does not require an account and does not collect, sell, or transmit your personal data. Article processing happens locally in your browser, and your reading preferences are stored locally on your device.

Whether you're reading news, research, documentation, essays, Wikipedia articles, blog posts, or long-form content, Zen Mode gives you a calmer and more flexible way to read on Firefox.

Less clutter. More reading.
