About this extension
TZone lets you switch your browser's timezone with one click.

When you select a timezone, your location and language settings automatically adjust to match. This is useful for developers testing location-aware apps, remote workers coordinating across time zones, or anyone who needs to see the web from a different region.

Features:
- Pick from the full IANA timezone database
- Fuzzy search to find timezones quickly
- Save favorite timezones for quick access
- Applies to all open tabs at once
- Works instantly, no page reload needed
- Clean, minimal interface

TZone does not collect or transmit any data. All settings are stored locally in your browser.
