I spent a few weekends building a Firefox browser extension because I was tired of my new tab page doing absolutely nothing useful.

The result: Weather & Clock Dashboard — a replacement new tab that shows live weather, a 3-day forecast, and clocks for any cities you care about.

What it does

Live weather : Current conditions with temperature, humidity, and feels-like for your location

3-day forecast : See what's coming so you can actually plan your day

World clocks : Multiple cities displayed in real time — great for remote teams across time zones

Search bar : Quick search without switching tabs

Dark/light mode : Respects your preference, toggles with one click

Why I built it
