Orbit от MonilMeh

Orbit adds keyboard-first browsing to Zen and Firefox. Scroll pages, follow links with on-screen hints, switch tabs, control page colors, and see every shortcut with ?. Press ; to turn Orbit’s page keys off or back on; typing in text fields is left alone.
Orbit also replaces the new-tab page with an editable launchpad, scratchpad, weather, and suggestions drawn from your local browsing history. No account is needed. History analysis and your launchpad and scratchpad stay in your browser. Weather uses IPWho to estimate your location and sends approximate coordinates to Open-Meteo for the forecast.
