Focus Mode – Hide Tabs & Address Bar by Alexis Demarecaux

Focus Mode turns any tab into a clean window.

One shortcut hides the tab bar, the address bar and the bookmarks, without going full screen, so you can keep your notes in another window next to it. Press Esc or the same shortcut and everything comes back exactly where it was. No account, no setup.

Free, forever

• The focus window: tabs, address bar and bookmarks hidden in one press
• Alt+Shift+X on Windows and Linux, Ctrl+Shift+X on Mac (Firefox keeps Cmd+Shift+X for itself). You can change it in Add-ons and themes → ⚙ → Manage Extension Shortcuts
• Works on every site, nothing to set up
• Seven ambient sounds to mix: rain, café, fire, forest, waves, white noise, brown noise
• Your daily counters: sessions, focus minutes, hidden tabs

Focus Pro: one payment of $7.99, yours forever (optional)

Some features require this one-time payment. It is handled by ExtensionPay and Stripe. No subscription, and the free features never expire.

• YouTube, X, LinkedIn and Reddit: hide the feeds, Shorts, recommendations, trends and promoted posts; text-only and search-only modes; daily limits. Everything is off by default, and the page always tells you when Focus Mode hid something.
• Pomodoro timer with auto-cycle and a session intention
• Site blocker
• Focus stats: streaks, levels, badges and a year-long activity map
• Favorites, quick capture box, distraction log, daily goal

Privacy

No analytics, no ads, no tracking, no account. Nothing about your browsing leaves Firefox.

Good to know

• On Linux, Firefox keeps this kind of window above your other windows (Firefox bug 1380184).
• Firefox doesn't let extensions run on its own sites (addons.mozilla.org, support.mozilla.org…), so Focus Mode doesn't open there.
