About this extension
WorldTab replaces your Firefox new tab with a clean, focused page built around world time.
WORLD CLOCKS
A row of clocks sits at the top of every new tab. Each one shows the current time, UTC offset, and how many hours ahead or behind it is from your local time. Clocks sort automatically by UTC offset. Daylight saving time is handled automatically — no toggles, no manual adjustments.
TWO MODES
Switch between Timezones mode and People mode with one click.
Timezones mode shows cities and regions you choose.
People mode shows your colleagues, friends, or family — type a name, pick their timezone, done. People in the same UTC offset are automatically grouped into a single clock block, even if they use different timezone names. For example, Belgrade and Paris are shown as one group during European summer time.
SEARCH
DuckDuckGo search bar in the center of the page. Type and press Enter.
TOP SITES
Your most visited pages appear as shortcuts below the search bar, pulled directly from Firefox.
SETTINGS
Open settings with the gear icon. Add, edit, or remove any clock or person. Search timezones by city name — type "Tel Aviv", "Almaty", or "Bangkok" and the right timezone appears instantly.
No accounts. No tracking. No external servers. Everything is stored locally in your browser.
Keywords: world clock, time zones, new tab, clock, international time, team timezone, DuckDuckGo, productivity
