Location Flags for X (Twitter) adds small country flags next to usernames based on the public "Location" field in their profile. It works automatically on timelines, profiles, and hover cards on both twitter.com and x.com.

Features:
- Shows a country flag or region icon next to X (Twitter) usernames when a location can be detected.
- Works on tweets, user profiles, and hover cards.
- Uses only the public profile "Location" field and local browser storage for caching.
- Includes a popup to enable/disable the extension and clear the location cache.
- No tracking, no analytics, and no external network requests beyond X/Twitter itself.

Privacy:
- All processing happens locally in your browser.
- The extension does not collect, send, or sell any personal data.
- Cached locations are stored only in your browser’s extension storage and can be cleared at any time from the popup.
