A calm, good-looking new tab for Firefox: a clock, your links and the weather on top of a background you like.
Get it on addons.mozilla.org
Backgrounds. Eleven animated scenes (waves, a solar system, drifting particles and more), your own picture, a random photo from Unsplash, photos for a keyword, or the Wikimedia Commons picture of the day. You can also have a different background at night that switches by itself.
Clocks. Up to three, each in its own time zone and labelled with the city, so "Tokyo · +8 h" is one glance away. Digital or analog, with seconds if you want them, and any font, color, size and shadow.
Weather. Current conditions, the next 24 hours and five days ahead, in °C or °F. The card stays small until you hover it. No account or API key needed.
Links and bookmarks. A grid of your favorite sites (keys 1–9 open them), and a bookmarks panel with site icons, pinned bookmarks and a search that shows where each bookmark lives.
Settings that stay out of the way. Everything is in one side panel. Right-click any control to reset it, and export everything to a file to move it to another computer. Available in English, Русский, Polski, Deutsch, Español, Беларуская and Українська.

Settings stay in your Firefox profile. There are no accounts, no analytics and no servers of our own. The page goes online only for the features you turn on:
| Feature | Service | What it receives |
|---|---|---|
| Weather | Open-Meteo | the city you typed, or your coordinates |
| Name of your location | OpenStreetMap Nominatim | your coordinates, once, after you press "My location" |
| Online photo | Picsum / Openverse | your search keyword, if any |
| Photo of the day | Wikimedia | today's date |
| Site icons | each site's own /favicon.ico |
a normal icon request |
| Site icons through Google (off by default) | the addresses of your links and bookmarks |
Fonts are bundled with the extension, so no font services are contacted.
Plain JavaScript modules, HTML and CSS. No build step and no dependencies.
