WorldTab — Team Clocks & New Tab 作成者: German Goncharov

WorldTab turns your Firefox new tab into a team time hub.

PEOPLE MODE
Add your colleagues, friends, or family by name and timezone. People sharing the same UTC offset are automatically grouped into one clock block. A green dot shows who is currently within their availability hours.

TIMELINE MODE
A horizontal 24-hour view of your local day. Each group gets a row with a colored bar showing their availability hours — so you can instantly see when your day overlaps with theirs. The current time is marked with a vertical line.

TIMEZONES MODE
Classic city-by-city clock view. Every entry gets its own block — useful when you need to see Belgrade and Tbilisi separately even if they share an offset.

AVAILABILITY HOURS
Each person has configurable availability hours (default 09:00–18:00 in their local timezone). Enable or disable per person. Daylight saving time is handled automatically.

SEARCH
Search bar in the center. Choose between DuckDuckGo, Google, Bing, Yandex, or Yahoo.

TOP SITES
Your most visited pages as shortcuts, pulled directly from Firefox.

SETTINGS
Light, dark, or system theme. English and Russian interface. Offset format: UTC+3, GMT+3, CET/MSK, or +03:00. One-click helper to also set WorldTab as your Firefox homepage.

No accounts. No tracking. No external servers. Everything stored locally.
